I have a windows 7 emachine and it would not turn on so i replaced the power supply it worked fine for 2 days now it wont turn on again. I'm getting nothingno fanno lights.can someone please help i just purchased this computer.

The main problem these days are that people are putting windows 7 on desktops and laptops that are 4 to 6 years old. They don't have the video card that is capable nor fast enough to care that OS. So go back to the system it came with and the problem will go away, or buy a newer computer.

Power supply is most likely your problem--many desktops with this issue have before it happens an issue where it has to be turned on several times and will finally come on and stay on.

The power supply in most cases is a unit that can be removed and tested (most shops charge little or nothing for this.)

If you are able to get it out look for bad filter caps on that board--some examples:



If puffy caps are found you have two choices---replace them all or if possible buy a generic power supply replacement............

In my opinion you have a faulty power supply, replacing only the fan may not solve your problem. Try replacing the power supply.

Try connecting a different power supply to it. If the same situation repeats, then it's an internal (motherboard) problem. If the problems go away, then the power supply needs to be replaced.

6 years... I'm surprised the PSU even lasted that long! The power supply is the cheapest part of the PC and usually one of the first parts to fail. Don't worry, a replacement power supply is not too expensive. Good luck!

Your eMachines features the cheapest power supply in the industry. I have personally replaced 6 of these. You can replace it with a factory unit for $20 or go to your local compter shop, and get a $40 unit that will last until you need a new computer.

( It says... 480Ws but I dont believe it )

$20:

Check the fuse on the inside of it and see if it is not blown, if not blown change it any way it may not look like it is blown but it is hard to tell, and see if that work.

Helo,

If the power supply from your friends old computer may not fave all of the correct plugs to power up your computer. You system needs 2 plugs going to the motherboard one with 20 pins and one with 4 pins. Besure you have the correct plugs. The second thing to check is recheck the friendss power supply in another machine. Last option is that when your power supply overheated and died that it damaged your motherboard and you may have to replace it too.

it can be a bad power suply ,just try replacing it. IF it dosent work check your hdd

remove all external and internal peripherls.

example for external: mouse, monitor, keyboard, printer.

Internal: hard drive, memory modules, video cards, modem (if there's any), optical drive or dvd drives.

just leave the motherboard, power supply and processor intact, try turning on the computer with out those components mentioned. see if you get a beep sound before it turns off, but if not the most logical part that needs to be replaced on this type of problem is the power supply if that doesn't work the next thing to do is replace the motherboard. hope that helps


hit me back on the results. thanks!

also in addition to the above, try reseating the ram chips..take them out individually and plug them back into their respective slots..might be the miracle cure..If the motherboard fan turns on, it might just be bad memory..replace RAM chips
