    So this time the problem started out as a simple issue. Whenever I bump the desk or move the keyboard out with too much force, the computer shuts off. Everybody told me that it could have been a loose connection so I checked it all and replugged everything back in. The computer starting working fine for about 5 hours then it just shut off randomly while I was playing a game. This time, though, it shut off without me bumping into anything. SO, is this a power supply issue? I'm using a 550-watt supply while running a 7800 GT. This is the right power amount so that's not my concern. And now the problem has gotten worse to the point where I turn on the computer and nothing shows up again. Windows doesn't load and the screen is on too. You here the fans and everything but nothing will load. All my parts from my old issue were replaced EXCEPT the power supply and CD-drive. I don't think it could be another loose connection b/c now nothing even shows up. Please help!!! :)

    Have you tried plugging into a different surge protector and different outlet?

    Sounds like you need to swap the power supply to me.

    Sounds like a power short or your motherboard is not grounded properly on the case.

    Unplug everything that uses power and take out all added cards EXCEPT your video card and turn the PC on. Try bumping it around a bit and see if it reboots. If that doesn't work and you're savvy enough you can try taking the motherboard out of the case and do the same test. However if scenario 1 works first plug each device in one at a time and do a boot to see if you can recreate the power failure so you can narrow down the culprit.

    Good luck
