Well, I’m having a bit of trouble with my computer. I try to repair computers for a living, and I usually do pretty good job of fixing whatever may be the problem. Before I go spending a bunch of money on a new video card, I figured I would run my situation past the geekier readers of my blog to see if there is anything obvious that I am missing.

So, it really seems to me that this is a video card issue of some sort. I was able to take the screenshot you see above, so I know it is not a monitor issue (unless Print Screen works much differently than I have been lead to believe).
So the question is whether or not it is drivers or the card itself.
I guess it could be heat acting upon the card. The card itself doesn’t have a fan on it, just a heat sink. So, I’ve got this nifty bracket that mounds on the screws that hold in the PCI cards. It holds a 120mm fan parallel to the side panel of the case, and blows air directly onto all of my cards.
My temps, while high, are not too far out of line for the system:
It is a Prescott, after all. I know the case temps are high, and I attribute part of that to poor quality sensors in the incredibly cheap MSI motherboard, and partly to the lack of top fan on the case. I plan on putting a top vent on the case as soon as I find someone with a Dremel.
So, it is a tad hot on the video card, but it has direct airflow over it, with some coming from outside the case. I can’t imagine heat is the issue, but of course, I may be wrong.
So how about voltages, you ask? Maybe the video card isn’t getting the right voltages. Here they are:
Alright, so the voltages are a bit off, but tolerable. You should have seen what they were when I had my old 350-watt PSU in there! I can’t imagine that voltages like these would be the cause.
Now I think I have heat and power covered. That leaves drivers and general card failure as my only options.
Since I am running the latest drivers, and this issue has happened with the current drivers, and my old driver (prompting the update), I would have to say my card is starting to fail. Unless I am missing something, I can’t really imagine any other cause.
