Update/Bump
For a few days, the card has been running fairly cool and well. Temps average 60c for the GPU temp. The room temp now is 79f, so the case temp should be close to that since the case is open and the minifan is pointed directly inside. The P4's temps are good too.
Today, just a few minutes ago, I was browsing a site and all the sudden, the image when chaotic just like how it did on my first post. Weird thing is, the comp has been running the coolest today. I did a hard shutdown and waited a minute and started er up again, it seems to be running fine now.
Question is, it may not be the heat as the factor now, but something else. What could it be? I was not on any 3D app or even watching a video for that matter (But I have done some games and watched some videos with no problem lately). And if the card is really messed up, then why can I still use it most of the time?
