Used Computers (Desktops/Laptops) What To Look For? by Christophe Catesson
Nowadays desktops and laptops are much more durable and dependable that they were just five years ago. Therefore, buying a used or refurbished computer is becoming more of a trend.
Suppliers replace their computers on average every 6 months and companies frequently upgrade their equipment. Buying one of these used or refurbished computers can save you a lot of money while still using a quite up to date technology. This is even more relevant if you are not a heavy user (i.e. most of your time on a computer is spent online, you may use a few standard applications once in a while). Even modestly priced computers will more than suffice for these types of demand.
Thinking about buying a used or refurbished desktop or laptop?
Buying a computer is not at all an easy job, one has look get detailed information of the available computers of good and reputed brands. One must take into consideration the size, color, configurations, features etc? While your computer should correspond to your personality and lifestyle, you should always keep in mind the reputation of the brand in the market. Brand counts a lot; you can render good service by the manufacturer if your computer is damaged.
Important handy Tips before buying a computer…
* Verify if the brand is reputed and always buy a good reputed brand. Read about customer service experience for that specific computer issues
* Check the warranty/guarantee of the computer (seek out computers which still have warranty/guarantee remaining)
* Compare the price of the new model in the market with what price your buying your used computer, try to get the best bargain. i.e. a two year old computer should not be bought for more than half of its original price.
* Check if the computer is outdated (if out of production it is difficult to get spare parts)
* Is the operating system current (Windows Vista/Windows Xp). Earlier versions probably run slower (windows 2000) and would not be advisable unless your needs are limited (i.e. web surfing, Word…). In any event, stay away with computers running on Windows 98 (granted you don’t find many anymore). Also be aware of Windows Vista. Many users are reverting back to XP and that is even more obvious in the corporate world. Why? Vista looks nice but doesn’t bring many technical improvements; therefore IT managers are not willing to implement something new when what they have works just fine. Some domestic users just don’t like the new way of navigation within the Vista Operating System.
* Check if the configuration of the computer you are buying is good.
* Check the speed of the processor. If possible start the computer and see how long it takes to fully turn on. If its slow just turning on, imagine the lack of speed once you start adding software..
Additional Tips for laptops
* Is the battery life good? (search for the computers with a very good battery backup (2 hours minimum).
* Check for the screen size of the computer your buying and see to it that it is not exceeding the Normal (normally the screen size should be between 15-17). Less than that generally translates in older computers and increases the chance of age failure. Once the screen breaks, you are often better of changing the whole computer.
* Review the connectivity of the computer (Network, USB, Video, Audio?) look to it that it has a good connectivity including wireless
* Check out the weight. Ensure the computer is light enough for you to carry (light 7pounds)
Where to buy used computers:
* Online auctions. Pro: Often offer the best prices. Cons: Cannot validate the accuracy of the described item. No warranty. Tip 1: Some companies will offer warranty for up to two years, the cost is about 12 of the purchase price. Tip2: Buy from sellers with great feedback, do not hesitate to contact the seller with questions prior to bidding
* Online marketplaces: Pro: Set prices and quantities - Sometime warranty is available. Cons: Prices can vary a lot, do your homework
* Craiglist.com Contacting sellers on Craiglist.com in your local area gives you a chance to meet with the owner and physically test the computer before the purchase
Where to buy refurbished computers:
Refurbished computers can be a great way to buy as they have warranties and are generally sold by manufacturers or companies affiliated with them.
* Manufacturers websites will tell you how to buy directly from them or from their authorized sellers. Pros: Warranty, established companies. Cons: Prices are higher than regular auctions (you pay more for peace of mind)
Buying a used or refurbished computer can be a great way to save money. If you use some of the advice discussed above you can avoid many pitfalls. One last thing concerning laptops, make sure you have a good bag to protect your computer from a fatal accident. Your bag should be big enough for a 17 inch screen computer as it is rapidly becoming the norm, you will probably change your computer within a few years, the bag you may keep a lot longer.
Good Buy!

How a Surge Protector Can Help a Laptop Computer by Stephanie Larkin
Electrical power spikes can be devastating to any electronic device, but the damage to a laptop computer can be even more significant to its owner because of the potential for lost information and reduced productivity. Safeguarding laptop computers with a surge protector (also called surge suppressors) is one simple and inexpensive way to lessen the risk of physical damage or lost information due to electrical surges.
Fluctuations in electrical service are common around the world. Known as power spikes, surges, brownouts, and blackouts, these fluctuations can cause anything from fire to data loss in an unprotected laptop computer. When power returns, it can come in a rush, rising significantly above standard household voltage levels to burn wires, overwhelm circuits and potentially cause damage to laptops, adapters, and any external peripherals that may be connected to the computer. Even when the power surge is not strong enough to knock out a system, it can slowly damage the computer’s components, reducing its reliability and lifespan. A surge protector diverts the extra voltage from a power surge to a ground wire, sparing harm to any connected electrical devices.
Most household appliances use 120- volt power (AC) - the level of electricity that you get from a regular electric outlet. Laptop computers covert 120- volt power to about 12 to 18 volts (DC) by way of an adapter that is usually located along the power cord. This conversion offers some measure of protection, but it never hurts to add the additional shield of a surge protector.
Surge protectors are inexpensive insurance for costly electrical gear. They also add functionality to most office environments, as they typically come in a power bar format that offers extra outlets. While most surge protectors are also power bars, not all power bars are surge protectors. Be sure to check whether surge protection is offered before purchasing a power bar. Power bars with surge protection may cost slightly more than a regular power bar.
Many office environments use surge protectors as part of their standard equipment configurations. However, portability is a key feature of laptops, thanks to their small size and alternate battery power, so laptop operators often find themselves using their laptops outside of the surge protected office. Ideally, laptops should be guarded by a surge protector wherever they are being plugged in, so a travel-size surge protector is a good investment. This is especially true in a hotel or large building where air conditioners, elevators or other equipment requires periodic bursts of large amounts of electrical power.
Not all surge protectors offer the same level of protection, and none can guarantee electrical equipment won’t be damaged if there is a severe power surge such as that caused by a nearby lightning strike. A powerful surge may also damage the surge protector, so try to find a model with an indicator light that goes out if the unit fails to function properly. There are several Underwriters Laboratories (UL) ratings (found on the label) that can help you choose an appropriate surge protector, such as clamping voltage, energy absorption and dissipation, and response time. Clamping voltage is the point at which electricity is diverted to the ground wire. Look for 330 to 400 volts. Energy absorption and dissipation is the amount of energy, in joules, that the surge protector can handle before it fails. The higher the number the better. A rating of 200 to 400 joules is adequate, but a rating of 600 joules or more will offer superior protection. Response time is the delay between the power surge and the surge protector’s diversion to ground. Faster is better, in this case, as the less time your laptop is exposed to the extra energy, the safer it will be. A response time of less than a nanosecond is desirable.
Power surge consumers who aren’t knowledgeable about electricity and UL ratings can also judge a surge protector by its price: more expensive models tend to offer better protection than the cheapest discount store models. Quality laptop travel surge protectors can generally be purchased for less than $50 (USD), and offer a variety of features including telephone and network/broadband Ethernet jacks, and universal plugs and sockets that will work in countries with electric utilities offering 100 volt AC service to 240 volts AC service. Some travel adapters have built- in surge protection that protects laptops as well as cell phones and personal digital assistant (PDA) devices. Most laptop surge protectors are designed with convenience in mind, and are compact and easy to pack.
The last consideration in purchasing laptop surge protection is the quality of the warranty offered by the manufacturer. Some companies will offer compensation if equipment is damaged by a power surge while it is protected with a functioning surge protector, but warranties vary, so read the fine print.

Get Greener By Recycling Your Computer Equipment by Vince Nitti
The rapid evolution of information technology is a double-edged sword. While constant improvements allow us to keep doing more in less time, the downside is that electronic equipment quickly becomes obsolete and needs to be replaced by newer, faster models. One obvious drawback of improving technology is the cost of replacing older models, but what happens to the old equipment? Many computer components are highly toxic to the environment, and virtually all electronic equipment utilizes some form of computer technology. What do we do with the computer we’re replacing? The group Local Self-Reliance estimates that about 75% of obsolete computers and other IT equipment is being stored, creating a time bomb waiting to go off. It will be a dark day for the environment when we all finally decide to dispose of this clutter.
Mercury, chromium, and lead are a few of the hazardous materials found in batteries, cathode ray tubes, and circuit boards. These toxins will be released into the environment if all this outdated equipment disposed of in traditional ways. Soil and water will be affected if this material is dumped in a landfill, and incineration releases toxic ash into the air.
This is why we shouldn’t simply trash our obsolete computers. Many organizations are dedicated to recycling old computer hardware. Recycling helps the environment and enhances quality of life for all of us. There are many volunteer and nonprofit groups that provide recycling services, recovering over 112 million pounds of valuable materials each year from old computers and other electronic equipment. Glass, plastic, steel, and precious metals can all be reused. Most of us don’t realize that even keyboards, CDs, floppy disks, ink cartridges, and power cords contain easily reusable materials. Some peripheral hardware can be utilized with a new computer, such as speakers and reusable disks.
Staples is one company that has instituted a green policy, where old equipment can be dropped off seven days a week for a $10 handling fee. Company spokesperson Mark Buckley estimates that in this country alone, 13,000 computers are disposed of daily.
According to Mark Buckley, of Staples, which has a green policy on accepting old equipment 7 days a week in a drop-off scheme, for a handling fee of 10$, estimates that 13,000 computers are disposed of every day in the U.S. While the company keeps many of the component parts, Staples hands off CR tubes and other hazardous materials to Amandi Services, which makes television components utilizing their own recycling technique. Another organization utilizing new technologies to complement and enhance the usual pulverizing and shredding is Creative Recycling. Their reclamation utilizes very efficient dust filters and negative air pressure in a controlled atmosphere. The output of this system includes various metals, plastic, and glass. The company aims to provide cost-effective solutions for government organizations and has invested millions of dollars in equipment in an attempt to lead the development of new recycling technology.
Not many people have noticed that recycling legislation has been passing in Europe for the last five years. That was when the Waste Electrical and Electronic Equipment Directive was drafted, forcing computer manufacturing companies to pay for the recycling of old equipment in a safe manner. Unfortunately, since the industry operates with very small profit margins, most people believe the costs will be passed on to consumers in the form of higher computer prices. The additional cost per computer could be as much as $50, according to industry analyst Gartner. And while most people wouldn’t balk at paying a small premium to have their old equipment disposed of properly, the European Union is requiring more stringent demands of green components in the future. This will also increase manufacturing costs in the short term, raising prices even higher.
There aren’t many companies currently recycling computers in England, but the computer companies themselves are beginning to step up and provide alternatives for recycling old equipment. Dell is one computer manufacturer pioneering new ways to recycle old computer equipment. Find out more about computer disposal and recycling by visiting their website at Link =”http://www.computer-recycling-center.com” class=”hft-urls”>http://www.computer-recycling-center.com.
Compared to Europe, this country is fortunate to have many local outlets for computer recycling. But don’t wait too long to drop off your old computer at a local recycler, because the cost is only going to get higher.

Acquaint Yourself With Computer Printers by Mack John
A computer printer is a device used for printing text or images on hard copy stored in electronic form, generally on physical print media like paper. Printers are designed to support both local and network connected users simultaneously.
Nowadays, modern printers can directly interface to electronic devices like digital cameras. Some printers that come with non printing features are commonly known as Multi-Functional Printers (MFP) or Multi-Function Devices (MFD). It integrates various functions of multiple devices into one. Such types of printers are extremely useful for small businesses and home offices.
As opposed to a traditional printer, a multi-functional printer is a combination of devices like Printer, Scanner, Photocopier, and Fax Machine. Likewise, there are numerous other types of printers widely available in the market. Let?s take a look at them:
Laser Printer: A laser printer works in a similar fashion as a photocopier does. It has a roller which is charged with electricity. A laser beam is passed to remove the charge from portions of the roller. The parts hit by the laser are powdered by the toner which is then transferred from the roller to the paper. Finally, the ink is baked into the paper with the help of a heater incorporated in the printer. People generally prefer laser printer because of its ability to give high quality output and high speed.
Dot Matrix: It has a print head that moves across the page. A dot matrix printer produces characters using a cluster of pins which press an inked ribbon to the paper, thereby creating a dot. Each character is made in the same way. Dot Matrix printers are relatively cheaper and durable. These qualities still attract businesses which use them as invoice printers.
Ink Jet and Bubble Jet: It works in a manner similar to a Dot Matrix Printer. However, its print head sprays liquid ink onto the page instead of pressing a dry ink against the page. Ink jet and bubble jet printers are better known as predecessors of laser printers. They produce better image quality and run faster.
>From inkjets to monochrome and color lasers, different printers are designed to accomplish different tasks. Companies like DELL, CANON, LEXMARK, BROTHER, EPSON, and HP HEWLETT PACKARD are most preferred when it comes to buying a printer. Nowadays, computer printer support is widely available on the Internet which saves you from taking it to any expensive technician for troubleshooting.

Get A Personal Loan To Buy Or Upgrade Your Computer by Melissa Kellett
Both the computer and the financial industry are very competitive, thus it is not difficult to find great deals that can save you a lot of money. Sometimes you lack the cash to purchase a new system or upgrade your current one. That?s why Personal Loans are the perfect solution to this kind of problem. Learn why personal loans are the best source of finance.
There was a time when computers where a luxurious item. Only those with a high income could afford getting one. Nowadays, the computer industry has evolved and new products arrive every day driving older ones obsolete. This has greatly reduced the prices but also created the need of upgrading or buying new equipment regularly.
Financing Your Purchase
Thus, the need for finance becomes more marked especially for those with a limited income. Using your credit card is always an option but not the cheapest one and sometimes not available for everyone. If you are buying a new computer, your credit card limit may not let you purchase it through that means. Sometimes your credit card limit would allow it but other expenses may have exhausted your credit.
Using a personal loan to finance the purchase is a much better solution for several reasons. For starters, the interest rate charged for personal loans is significantly lower than that charged by credit card companies. Credit Card holders are used to paying a two digit interest rate that can get as high as 25% while those who request a personal loan may have to pay, in the worst scenario, an interest rate of 10%.
The amount of money you can obtain through a personal loan is significantly higher than your credit card limit (Often, the difference being 5 to 1 in terms of loan amount). If your credit card limit is $1500, chances are you can easily get approved for an unsecured personal loan of $7500. Most pre-approved loan packages that come along with credit cards and an overdraft agreement for your bank account feature that amount ratio.
Another important advantage is that you can repay the loan in many loan installments even lower than the minimum payments on a credit card balance. Moreover, since the loan installments usually come with fixed amounts you can be sure that when the last payment is due, you will have cancelled all your debt and you will have become debt free. Paying credit card minimums, on the other hand, often implies paying only interests while your debt?s principal stays unaffected.
What If I Have Bad Credit?
If your credit is less than perfect you needn?t worry. Most stores that offer personal loans specifically designed for buying their equipment and other non-traditional lenders feature personal loans for people with bad credit, no credit at all and sometimes you can even get approved if you have recently gone through a bankruptcy process. What you need to do is request loan quotes from different lenders and compare rates and fees. Make sure to do this, especially if you have bad credit because the interest rate charged to those with bad credit tends to be higher so it will not hurt you to get the best deal possible.

How To Troubleshoot Your Computer Hardware by Steven Stoddard
There could be many reasons why you?d want to troubleshoot your computer, well, one actually and that?s because something is not working right. The process of troubleshooting is something you learn after working for a long time with computers. Often enough when there?s a problem, nothing is going to explicitly tell you what is causing the problem and how you can fix it. By taking logical steps and walking through the process of troubleshooting you should be able to solve almost any computer problem, software or hardware related. It involves identifying the problem(s), finding the cause of that problem, determining the solution, executing that solution, and testing and checking that solution to see if it solves your problem.
As an example let?s say one day while using your computer the screen suddenly turns all black and you can?t see anything. We found a problem now what would be the first step to take to fix it? First check to see if the monitor is on and is receiving power, most monitors when they have power, but no connection or connection problems with the computer will display a message that says this monitor is working, but make sure you check your cables. So the next logical step to take would be to check the cable to make sure it is properly connected and secured to the VGA slot behind your computer case and to make sure the monitor cable is plugged into the monitor. Now, here?s where you have to decide what would be the next best course of action to take. you could either swap out your monitor with another monitor that you know is working to see if the problem is the monitor itself and nothing else or you can try to see if the problem is your graphics card. If your replacement monitor works, good, then you know your culprit is a bad monitor and you?ll most likely have to get a new one, because monitors are dangerous and too costly service. If the replacement monitor you used shows up a black screen as well, the next thing you?d do is check to make sure the graphics card is properly seated in the motherboard, if it is and the display is still not showing up, then swap out the graphics card to see if your problem is fixed.
Generally there are only so many steps you can take before you solve the problem and everything is back in order. Make sure that before you start testing and swapping out parts that the problem wasn?t caused by you changing a software setting in Windows or some ambiguous option in the motherboard?s BIOS that causes your problem.
Motherboard
The motherboard is the heart of the computer, every part of the computer relies on the motherboard to function correctly. It maintains connection between every PC component and ensures that things are operating smoothly between them. Many signs of motherboard failure is that the computer won’t boot up, not reaching the POST test, erratic system behavior, different combinations of components not working. Because everything is connected to the motherboard certain parts may or may not work correctly if the motherboard is faulty so be sure to test those parts before thinking they’re dead and getting new ones.
Be sure to do a visual inspection of the motherboard to make sure all cables are seated properly, the fans are spinning, and that the CMOS battery is in it’s proper place.
Also check for any broken or leaking capacitors, those can immediately render a motherboard dead.
Make sure that all of the jumpers are set correctly as well, you should be able to find jumper information in your motherboard’s manual, and if you don’t have the manual you should be able to find the manual on the Internet at the motherboard manufacturer’s website.
Many of the problems caused by a bad motherboard is also similar to problems caused by a faulty or dying power supply, so be sure to check if the power supply is faulty or swap it out for another to see if your problem is fixed. If you have a spare motherboard you can try swapping out the motherboard to see if that solves your problem, if that’s the case then the motherboard is most likely faulty. If you think the motherboard is faulty and it is still in warranty you should be able to send it back to the manufacturer for a new one with no hassle, sometimes they might even pay for the shipping & handling if it is a big problem that is happening with a certain line of motherboards. Make sure that when you open a motherboard you keep all of the packaging and the box, and if there are any stickers that will void the warranty if removed make sure you do NOT remove them, so that way it is easier to send back.
Power Supply
If you suspect your power supply is giving you trouble, make sure you check it out fast, because power supplies can make trouble with the rest of your system as well. Irregular voltages sent from the power supply can short circuit and overheat your components thus frying them and making them unusable. Some faulty power supplies have even caught on fire, but if you?re lucky it might just smoke a little and start to smell. A few signals that your power supply is bad or is going bad would be erratic and seemingly random system behavior like system hangs and crashes, and burning smells along with smoke.
If you recently upgraded your system or added new hard drives, disk drives, a graphics card or anything for that matter, be sure to check if your power supply is being overloaded with hardware. A good way to check is to use a power supply calculator. One time when I upgraded my system with a new fancy PCI Express 16x Graphics card, well it was fancy back then, I had problems with the graphics card performing while in 3d games, it was all due to my power supply being unable give it enough juice on the 12v rails so it performed poorly and didn?t act as it should have, I even swapped out the graphics card for another one believing it was bad, after checking the manufacturer?s forums it seemed like a lot of people were having problems with faulty cards, so I figured mine must have been faulty too. After getting the new card it seemed like it performed better for a little bit longer, which could?ve just been some optimizations they did to circuit board. Seeing how they sent me an upgraded version of the same card, but it wasn?t until I checked my power supply wattages that I found the real culprit.
The first thing to do to diagnose your power supply is check the power supply connectors, make sure everything is plugged into the motherboard and the power cable is plugged into the power supply, you wouldn?t believe how many people forget to plug in their computer. Many power supplies also have a power switch on them so check to make sure that no one accidentally or purposefully switched it off maybe for a prank. Check the fan to see if it is spinning at the correct speed and if it?s dusty vacuum it out. Determine if the power supply cables are giving out the right amount of voltage, if you computer will let you boot you should be able to check them in the BIOS menu to see if the correct voltages are being given. Normal power supplies give +3.3 volts DC, +5 volts DC, -5 volts DC, +12 volts DC, and -12 volts DC.
Memory
Faulty RAM can have many adverse effects on your system. Constant lockups, computer rebooting, memory error message (duh), system crashes, and sometimes refusing to boot up are all signs of memory errors. Though, these are also signs for motherboard, hard drive, and power supply problems too. Luckily for you if you think your memory is subject to causing a disruption in your system there are programs that can check the memory for it’s performance and to see if it is generating any errors.
Memtest86+ is an amazing memory diagnostic program. It is based off of the original Memtest86 that has been around since 1994 and is used by system-builders, average joes, and professionals in the IT world. It’s a standalone memory check test which means it can be easily run without a bootable operating system, that’s good if you can’t just seem to get your PC started and want to rule out your memory as quickly as possible.
How To Use Memtest86 With Your Floppy Drive To Test Your Memory
First go their website at www.memtest.org and select the most appropriate version to download. You can download the bootable iso or the Pre-compiled floppy drive depending on whether you want burn a CD or use your floppy drive. We’re going to go into details on floppy method.
Open up the .zip and extract the files to a folder, then click on install.bat, you will be asked to ?Enter target diskette drive:?. Type A and hit enter then it will ask you to insert a formatted diskette into drive A: and press -Enter-: after you hit enter it will write some files to your floppy so you can boot your computer with the floppy to test for errors.
After the floppy has been formatted with Memtest86+, leave the floppy in your floppy drive and reboot your computer. Remember to set your floppy drive as the first boot device in your BIOS menu.
The program will automatically load and perform the memory diagnostic tests on your computer. During the testing if there any errors they will show up and at the end of the test it will tell you how many errors you’ve had.
After testing your memory if you receive any errors you should make sure that your memory is okay either by swapping it out and seeing the problems still occur or try your memory in another system. If the memory passes the tests then you proceed to troubleshoot something else with good faith that your memory is fine.
Hard Drive
The hard drive is that ultimate safe to everything important on your computer. It keeps all of your information, files and folders, music, videos, favorite websites, and programs. With a bad hard drive there’s no reason to have a computer. In terms of fixing a computer if the hard drive isn’t salvageable then most people don’t even want to bother with the rest, because their computer is probably a piece of junk that has been handed down from time to time. Generally when a hard drive is about to fail it’s usually years down the road from first acquiring the computer. So the next best option rather than replacing the drive is to just buy a new computer, or build a new one, because your old one sure is probably not running as fast as it used to.
Luckily before your hard drive kicks the bucket there is usually a few warning signs:
Abnormally slow file transfers
Problems with booting, especially when Windows is being loaded
Corrupted files
Disappearing files or folders
Loud hard drive noise is a good sign that there is a mechanical problem going on inside
If your hard drive exhibits any of these signs be sure to transfer all of your files to another source immediately, and do not continue to do day-to-day activities with that hard drive. If it doesn’t show any of these tell-tale signs, however you have a gut feeling that your hard drive is on the brink of destruction you can try using many different drive testing utilities available on the internet. The hard drive manufacturer usually has at least one qualified tool that you can download from their website and run. Other ways to check the health of your hard drive involves running the Windows Error Checking tool by right clicking on your hard drive in ‘My Computer’ then selecting ‘Properties’ and going to the ‘Tool’ and clicking on ?Check Now?, or checking the SMART status located in your motherboard’s BIOS. SMART stands for Self-Monitoring, Analysis and Reporting Technology. Most motherboards nowadays has this technology. It should be automatically enabled in your BIOS, if it’s not then your hard drive won’t get checked. What it does is on boot up it will perform quick tests on your hard drive to ensure it is running correctly and it will continue to monitor it for any errors or abnormal problems that may occur as long as the computer is turned on.
Monitor
Watching movies, videos, playing games, and looking at NSFW material are all amazing things we can do on our computers. Yet there may come a day where you just want to get on your computer and relax in your computer room looking at all that NSFW material you have bookmarked under the ?Special Sites? category, but you can?t because your monitor won?t turn on. No, you don?t frump and punch holes in the walls to look for an outlet for your rage. You troubleshoot it, and hope to god that your monitor isn?t broken!
When diagnosing a screen problem, half the time it?s usually something very easy, like a cable coming loose, or the monitor getting unplugged accidentally; unfortunately the other half the time it?s probably a problem that?s related to your monitor being old, or a problem that?s related to your graphics card instead. So you may have to diagnose both items at the same time to see which solves your problem.
First, check all your cables, I know this is probably getting a little old with the checking connections and everything, but so many computer problems can be avoided if people just remember that their computer isn?t always going to stay the same way they left it. A foot could kick out a cable, a dog or a cat that got to curious, or almost anything can render half your hardware useless.
After checking all your cables, make sure your screen has power, if it has power and shows a message such as ?This monitor is working correctly please check your cable? and shows bars of color on the screen, that means that your monitor is not getting a signal from your computer. Try swapping out the monitor for another one to see if it still says that message. If it does then that means the problem is most likely something to do with your graphics card not seated in the motherboard, or just isn?t working properly, you may want to try swapping out another graphics card to see if that solves your problem.
Generally monitors don?t have that many diagnosable problems. Either they work and they work well, or they don?t work and you have to replace them. When working on a monitor you should never open them, they aren?t meant to be serviced and contain high charged capacitors that hold lethal doses of electricity. We wouldn?t want to read about a computer guy in the obituaries now would we?
Graphics Card
The glorious graphics card, it?s an amazing thing really. It makes all those pretty HDR (High Dynamic Range) pictures look just that good, it keeps your games running smoothly, and your videos in HD. Yet these things can be pains when they?re just not working right, because if something is wrong there?s not a strict hardware or software solution, you have to analyze the current situation to see what?s up.
First and foremost if you?re having any problems with your graphics card, probably the best thing to try to do first is see if there an updated driver for it at the manufacturer?s website that may solve the problem, or if there isn?t an update try uninstalling your graphics drivers and reinstalling them this little action can solve so many problems.
If there?s little jaggies or weird colorful mishaps known as artifacts appearing on your screen you may want to check the temperature of your graphics and make sure is getting enough cooling, and that the fan is working properly. If the cooling checks out okay you may also want to check your power supply ratings to see if it is giving enough juice to your graphics card. Nowadays most graphics cards need a lot of power on the 12v rails, make sure your power supply can give you that power that the graphics card needs.
Sound Card
Some of the typical problems people have with sound cards is either A) no sound or B) no sound. Sounds card typically aren’t very expensive so having to replace one if the current one isn’t working is no big deal. However, if you’re one of those audiophile types who expect 100% original recording quality with your $300 sound card replacing one of those is as expected a lot more harder to do.
Sound Card Troubleshooting
Check speaker cables make sure they’re all connected and plugged into the right spot on your sound card. Also check the speaker’s power cables.
Make sure windows volume is turned up and the volume is not muted, also make sure that you have all the wave and playback volume turned up and not muted. If you have ‘Digital Output Only’ checked in your Advanced Controls for Playback Controls, try unchecking it to see if that solves your non-sound problem. I found that if I have that checked my sound card won’t give me any sound.
Try reinstalling your sound card drivers, also try checking on the internet at the manufacturer’s website for any updated drivers that may be available. They increase your sound card’s compatibility with your system.
If the previous tips didn’t help, then you may just have to replace your sound card, or atleast swap it out for another one to see if it might be a problem related to your sound card’s connection to the motherboard instead.
Processor
The processor is the actual thinking part of the brain of the computer. It does all the calculations needed to make a computer run, and does them all in split second timing. It determines how fast your computer generally runs, and most of the time is a bottle neck for systems that have had everything upgraded except the CPU.
If your processor?s not working, it?s not the end of the world, generally most processors that work correctly for a few weeks, should work correctly for the rest of it?s lifespan, which varies from 5-10 years or so. As long as you?re not overclocking the processor or letting it overheat too badly your processor should be fine, and it could just be a BIOS setting that?s messed up, or a jumper setting, but for kicks just check to make the processor is seated properly and the heat sink is attached to the processor and the motherboard. The heat sink should be attached tightly to the motherboard and not have room to move about, you should be able to pick up your motherboard by grabbing onto the heat sink without any problems. Check in your motherboard manual to make sure all the jumpers are set correctly for your type of processor. Any jumpers set incorrectly can cause the processor to not work, or function correctly or at it?s optimal speed. Also check the heat sink to see if it is cooling off the processor, if it?s not doing a very good job you may want to look into investing in a better one that gets the job done.

How to Find An Effective Computer Work From Home by Daegan H. Smith

Choosing too many work-from-home opportunities will divide your attention with too many concerns. And that would cause you to have divided income as well.
The best and the most profitable business around is still the selling business. Companies earn through selling their products or promoting their service. And if you partner with flourishing company, their success is likely to brush off you. So the choice of your company is very crucial. It is only important that you select a company that has a great future and your potential for growth is secured.
The compensation that these companies give their agent is an essential factor to consider as well. You should be paid a good amount in order to build an empire. The company that has the most creative way of paying commissions is the one that you should choose. The more streams of income they have, the more chances you have from earning through their opportunity.
However, it is essential that the company really have the ability to pay you back. Some companies are very bold in showing their agents the different ways to earn.

You can choose according to your likes, preferences, experiences, and expertise. The more you know about the opportunity, the better you will perform on it. If you like the products, you will sell it easier. If you know about the process and the product, you will be able to show your customers the advantages of using them instead of trying anything else.
The real key in generating massive income from the internet or through your computer is investing your time, effort, and knowledge on it. Without actual hands-on experience on the job, you won’t be able to get the income stream that you really want. Be sure that you learn everything about the company and the rest of the processes around it. This would allow you to formulate the right strategies that make allow you to earn the best possible way.
Support is also important. Be sure that the company you will be joining has lots of tools, resources, and community that you can take advantage of. These tools could help you a lot without requiring you to make additional investments.
If you are new in this type of business opportunities, especially in MLM’s, try to join something that virtually has no start-up costs. This would allow you to just have the feel of the entire business without losing anything. After you know the ropes, then you should be ready for bigger risks and for bigger income.

Finding Computer Home Based Business that Fits You by Daegan H. Smith
If you are a homemaker who is looking for a way to earn money off your computer, you have come to the right place. Finding a computer home based business that could generate lucrative income for you should be a lot easier now, given today’s digital age. Almost everything can be done online or through the computer. You can sell stuff, contact friends, and do your banking at home. Indeed, computer had made life much easier.
Now, computers can be used to add household income. With the many online opportunities you can try, earning a few more dollars everyday through the internet is very possible. One way to use your computer in a home business is through MLM or multi level marketing. This is an online earning opportunity that allows you to enjoy residual income sometime in the future.
All you have to do is to invest a good percentage of your time and energy to the business now and you will definitely reap the rewards of the future. There are a lot of MLM opportunities today. And by far, it is the easiest way to earn big bucks while surfing the internet. It works because of its structure. And that’s where you are going to invest most of your resources.
For those who still don’t know, MLM is the process of promoting a product or a service and recruiting others to earn. Basically, you will earn two ways. Most MLM companies carry a product or a service. These are the things you are set to promote. If in the market the product costs $50, you only get to purchase it at $40 or lower direct from the MLM company who distributes it. For every sale you make, you add $10 to your pocket.
Now that part is called hard selling. A lot of people don’t like to sell anything, whether it’s online or face-to-face. For those who don’t like selling at all, that’s okay, because you can earn the other way. And that would be through recruiting others to join under you. Between the two, this is the easier way to earn through MLM programs. All you have to do is to invite other people and that’s it. You will be able to earn from their earnings as well.
If your chosen MLM program has some sort of registration fee, then you will be paid for your every recruit. Some companies can pay for as much as $5 per downline or even more. Plus, if your downlines are able to sell a product, you’ll earn from that too. Basically, you will be earning for the every activity your active downlines makes. If they make money, you make money. So if you have a good number of them under you and they are really performing on their tasks, you really need not promote the products yourself. All you have to do is to wait for your check to arrive as you let them all do the working.
Some MLM programs provide compensations to deep as three to four levels. This means that you can earn from your downline’s downline too. The key to earning through this computer home based business is to choose the most lucrative program, invest some time and effort, and manage your downline so that you’ll earn big while working less.
