so my computer has been acting really strange lately. if u remeber, my mouse was all jacked up before (i posted a topic about it for help)

but now my computer wont stay on for more than about 20 minutes. It started out one day that it just wouldnt boot up, but then i started it in safe mode and checked everything, and then the computer could boot up normally. but it still wont stay on for any length of time. i updated all my virus protection and spyware software and im scanning my computer a lot but it wont stay on long enough to complete the scan.

Im thinking that its a power supply problem, for i have had a problem with it before, however a few tech guys i talked to think that its some kindda virus.

if anyone is good with this stuff, i would really appericate your help

Maybe overheating problem? Check temperatures right after shutdown in your BIOS (press del or F2 when the comp counts its memory).

If it's power supply disconnect you graphics adapter and use the onboard one. If the comp stays on then it's probably your power supply.

Processor could be overheating. It will shutdown if it gets to hot. Check your fans.
