Hey guys i signed up to this forum because I'm desperate for help. I've had this comp for the last 2 years and its never had any problem this big, but suddenly today its started crashing at random times, so often that i can't even use it. I don't know much about computers but the basic speccs are:
Windows XP x64 bit
Quad core
4gb ram
nvidia geforce 8800 gt
Sometimes it can crash while I'm still starting up the computer, but at other times i can start it up and it'll only crash when i turn on a heavy program, eg: a game.
90% of the times when it crashes, it has these strange blue dots across the screen, if thats relevant.
Oh, and also when it crashes it stops making any noises (i mean the humming-ish sounds from the comp stop). The screen just freezes, ctrl alt delete doesnt work or anything (occasionally though i can move my mouse, but clicking doesnt work).
It COULD be a virus i guess, because my anti virus expired 2 or 3 months ago and i haven't replaced it... just trying to give you guys as much info as i can.
I tried using CCleaner to clean the registry and everything, but that didn't help as far as i could see.
Please help asap guys!!
EDIT: Final note, the thing thats strangest about how it crashes when i turn on a game, is that usually i can have Limewire, Mozilla firefox and about 2 or 3 games on AT A TIME without it crashing. Now even having mozilla and 1 game on can crash it (and thats if i'm lucky).
