    I have the same problem. I took my computer to Best Buy Geek Squad twice. The first time, they got it to start fine and ran a scan. They could not find any issues with the hardware or software. The second time I took it back, they couldn't get it to power up. They tested a new power supply and still could not get it to start. They said it must be an issue with the motherboard and that it would cost around $300-$400 for them to fix it. Their suggestion was to buy a new computer.

    I have the exact same problem... Geek squad is an absolute joke and is convinced that viruses are the cause of the problem. I tried to argue that a virus could not stop it from completely allowing the computer to start to boot. This happened right after I installed a windows update, Geek squad diagnosis shows no hardware issues. Has anyone gotten theres to work?

    I wanted to clarify that Best Buy determined that the Power Supply was not the issue when they hooked up an alternative power supply the same problem ocurred.

    I wanted to clarify that Best Buy used an alternative power supply and it was definitely not the power supply that is causing this issue.

My satalite was disconnect and then back on well then my tv comes on and in a flash it's off will not stay on it has a picture.Dish said i need a surge protecter.

A power surge due to lightening may have damaged the switching power supply. You will need to change the power supply module inside the TV. Normally, such power supplies have surge protection built-in, however, some surges are too powerful and could damage capacitors and crystals in the power supply module.

No power

There are quite a few possibilities here. Do you leave your computer on while you're not home? If so, it's possible the computer overheated. If that happened, most likely you processor is damaged, and will have to be replaced. There may have been a power surge, which could have damaged the power suppply or the motherboard. It does nothing when you push the button? There's also a remote chance the switch is merely broken... though I can't say I've ever actually seen that happen. If it does absolutely nothing, it's most likely the power supply, however. If the motherboard or processor were bad, it would probably beep when you tried to turn it on. Not definitely, but probably.

Computer turns itself off and on, and it runs dog slow

Could be a virus. I had a similar one, and I had to format harddrive and install windows from scratch (was not recoverable). if you can get logged into windows, go to microsoft and download their free virus protection. if not, go buy a new emachine.

Mother board heats up and computer does not start

Does it start up at all ? Will it start up in Safe mode ?

Heat will cause computer components to expand sometimes not being able to make connecting to the hard drive. Could be a problem with the Hard Drive or the Hard drives PCB Motherboards can go bad for many reasons, although there are a few common culprits. Among the most common causes of motherboard failure are excess electrical shocks, physical damage, or excess heat. Some of these dangers are inescapable, and may vary in likelihood depending on your computer model. Fortunately, there are some simple steps to protecting the computer's motherboard, or mainboard, as it might also be called.

Signs of a Failing Motherboard Detecting the difference between a failing or failed motherboard and other failing components can be difficult. This difficulty arises because all the components of a computer are plugged into the motherboard. Thus, if you are having trouble seeing the screen, it could be that the motherboard is failing or that the video card is failing. For this reason, any part of the computer failing can be a sign of a motherboard failure. However, there are some more specific indications that the failure is the motherboard. These include the system randomly powering down, all the components of the computer powering up without a live image appearing on the screen and only certain components of the motherboard working. b> Causes of a Failing Motherboard b> As with most computer components, the most common culprit when a motherboard fails is heat. All computer components are particularly sensitive to heat, and the inside of computer can become quite hot. Over time, this wears out the motherboard and can lead to its failure. A second common cause of motherboard failure is electrical damage. Commonly this occurs during computer maintenance such as installation of new peripheral devices. During maintenance, if the technician has static electricity built up on his or her hands, it can discharge into the motherboard, leading to a failure. Electrical surges, such as those created by lightning striking a power line, can also lead to motherboard failure. This is most commonly prevented by using a surge protector, but some surges are powerful enough to overpower the surge protector and destroy the motherboard. The last common cause of motherboard failure is physical damage. This can be in the form of water damage or actual physical impact. Although the motherboard is typically well protected, a strong enough hit to the computer case or the introduction of water into the case can lead to motherboard failure. b> Diagnosing Motherboard Failure b> Determining that the motherboard is the cause of a particular symptom can be difficult. Although specialized tools exist to determine if a specific component has failed, the easiest method for determining which components are damaged is a simple bench test. This does, however, require having a second computer, or at least extra components. The method for this is to determine what possible causes could lead to the symptoms of motherboard failure. For example, if the system shuts down randomly, it could be the motherboard, the power supply unit, or connecting cables. In this case, you could plug the power supply unit into another system that is known to be working and if the problem persists on the other system, then the power supply unit is the likely cause of system instability. Similarly, if the computer powers up but fails to display an active screen, you can move the video card into a second, working computer and determine if the video card is bad. Then try using the good video card from the second computer in the damaged computer to determine if it is only the video card or if it is also the motherboard. Although this method is not foolproof, it is effective. b> Preventing Motherboard Failure b> A few simple steps can be taken to ensure the motherboard does not fail. While a motherboard may fail anyway, simply due to age or unforeseen circumstances, it is less likely to fail if you take a few simple precautions. First, ensure the computer is in a stable location where it will not be knocked over and will not be likely to have liquid spilled on it. Second, if any maintenance is performed that will expose the motherboard, use an antistatic wrist strap or discharge any static electricity before working in the computer by touching a grounded metal object. Third, keeping the motherboard clean and free of dust can ensure that it continues working, although some computer manufacturers do not allow the users to open the case during the warranty period. Last, ensuring you use a quality surge protector can prevent the motherboard from being destroyed by power surges. b> Laptops Laptop motherboards are more exposed to damage than desktop motherboards. Although they tend to stay cleaner, they are more likely to be exposed to heat due to the small case. They are also more likely to be exposed to impact since the computer is being regularly moved. When transporting a laptop, it is crucial to use a case designed for laptops that will prevent blunt forces from hitting the laptop. Also, many laptops have vents on the back and the bottom. As cooling the inside of a laptop is much more difficult given the confined space, ensuring that these remain unblocked while working on the laptop is critical. Learn where they are on your laptop and ensure you leave them unblocked while working and the laptop's motherboard should be effectively cooled. Hope this helps.

Power supply malfunctioning

Most surge protection power boards will protect computer equipment from mains spikes and surges.
A better and more expensive solution is to use an uninterruptible power supply (UPS). These units provide surge and spike protection and also provide power in the event of mains power failure.
Make sure you select an UPS model that meet the power requirements of all your computer equipment that is connected to the UPS with a mains down time of say 1/2 hour to give you time to shut down your computer in an orderly manner.

Hi all...!!! Power failed and came back minutes later. Can't start HP Media Center M7060n Green light on back flashes slow when power not connected, slower when power cord connected but I press the ON...

On HP computers, I believe that this means that the power supply or the motherboard is bad. I assume that the outage was due to the thunderstorm and you may have received a surge. In your manual, there should be diagnostic light codes where they will outline the exact meaning. Again, to the best of my knowledge, this means that there is a bad power supply or a motherboard.

Gateway 505gr became unresponsive, on reboot windows cannot load

Hello guys,
This problem would arise only when the motherboard doesn't work properly. Check with your nearest gateway service center to get your CPU work again. That would be the only thing to be done.
