Ok hi, im back again.
Im getting a BSOD every like 10 minutes sometimes, since my comp was turned off for the night right now it works ok, but who knows, it can happen any second.
I wrote down the error that Im getting.
STOP: 0x000000F4 (0x00000003, 0x866A8500, 0x866A8674, 0x80501142).
I wasnt installing anything lately...but somehting makes me think the video driver is a little corrupted or whatever. dont know, but i looked at other threads and maybe some of you can figure out the problem by the error.
