Yesterday I played crysis on all high settings except for shaders on Medium, at 1024 x 768 and I was getting from 40-50 fps.
I left the computer on and went to sleep while it downloaded Killing Floor.
And immediately I whipped out fraps and began recording. My game then had episodes of freezing, and when I tried to alt+tab out, I found that my whole computer was frozen. After closing killing floor, my computer kept on freezing until it became unresponsive.
I checked atitool for artifacts and there were none, although in crysis I noticed some graphical glitches, like random polygons being rendered in the sky for a split second, and things like that. The idle temperature was 47 c, and when it was using furmark or crysis or any game it went up to about 71 c maybe higher.
Could the system instability be caused by overclocking the card? Or is there something else I need to be worried about?
I had to manually turn off the computer and turn it back on twice. The first time it froze at the bios screen, like it always does when I have these problems.
