Hey all, recently in the past three days I have noticed my computer has started to freeze up completely every now and again. Doesn't matter what I'm doing although it seemingly happens more often when I'm gaming (not even too intensive games, like Warcraft 3, Americas Army, etc.).
The computer will freeze and the sound goes into a constant loop or starts going "ZZZZZZZZZZZZZZZZWHWHZHWHWH" (you get the picture). I then have to restart the machine and it will run fine for maybe even hours, before then freezing again.
I just can't work out what it is, nothing has changed within the past three days hardware wise, I have all the latest drivers, nothing is overheating (check both CPU and GPU regularly).
Any ideas? Any help would be GREEEAT, this is driving me insane.
(P.S: I have run every virus and spyware scan in existance and all is green and clean)
