My PC freezes once or twice a week leaving me no option but to restart. I have no idea what causes this. I bought it 3 months ago and use it only for gaming and internet.
I scanned for viruses using Norton 360 and found nothing.
Specs:
Win7 ultimate
gigabyte p61 s3
8 GB ram corsair
galaxy GTX 560 SE Nvidia
1 TB seagate 5400 RPM
PS: Windows was not genuine when I bought the computer, but suddenly it became activated by itself.
