I've had my computer for about a year now (was not new when i got it), and it's been fine until now. Suddenly it will just shut down for no apparent reason and it won't turn back on. I leave it for maybe half an hour and i can use it again for maybe an hour or maybe a few days, but then it will shut down again for no reason.
It actually HAPPENED right after i downloaded a file, the obvious THING would be that the file had a virus with it, but i did a virus SCAN, spyware, ad-aware, and nothing. (note i used AVG free edition for virus scan, maybe it didn't pick up the virus?)
ALSO, when I try to start it back up right after it's shut down sometimes it will jsut come on for a few seconds and then shut back down, but sometimes it will keep making the sound of it just starting up and do nothing until i shut it down.
Anyone have any ideas on it?Overheating
Power Supply failing
Bad RAM.

DLoad motherboard monitor and check your temps.
DLoad and run Memtest to test the RAM...let it run for awhile...any errors and the RAM has GONE bad.
PSU ...replace. Don't buy a cheap one...they are headaches.
