At first I thought my video card was over-heating, so I downloaded some GPU monitoring software and noticed it almost never goes above 50C. I also downloaded the FurMark GPU benchmarking software, and I have never received an error while running this graphic-intensive program. The GPU will rise to about 100C during this testing and not malfunction.
Also worth noting, I suppose, is that I'm running all of my games and Firefox off an older hard drive. My newer system doesn't have the internal hookups (IDE I think) only serial ports. So, I'm running a serial internal hard drive inside my case, and another internal hard drive in an enclosure case, attached through USB.
Here are some screenshots of the problems I'm having. Thanks for any help with this issue.
