Ok, so I recently just reformatted due to a nasty virus and I'm having a problem keeping my computer on. After I initially reformatted, I wasn't having any problems, I downloaded Kaspersky and was looking for some drivers to get my computer fully operational again. Shut it down for the night, and the next day when I turned it on, it began the boot process as normal, got to the windows loading screen(xp, btw) then just powered down completely. I turned it back on, and it shut down again, but a little sooner this time, and a little sooner again the third time which made me think it was over heating. checked my 2 case fans, powersupply fan, and cpu fan/heatsink and everything was working properly so I applied some new thermal compound to the cpu. It still shut down. So currently I'm running on a sort of modified bench test... All that's plugged in right now is the hard drive, wireless card and 1 stick of ram. Even with only these I still had some trouble getting it going. I'm honestly suprised it's still running right now. I have no idea what else to try. I'm completely out of ideas at this point so if anyone could help me out here that would be amazing!! I'm trying to do online courses for school so not having a computer makes it a little difficult.
