I need some help here. My card has been running fine (EVGA 8800 GT) for the last month since I got it. I've recently been looking at possibly overclocking it, but haven't even started the process. I downloaded some programs such as rivatuner, atitool, and gpu-z to just get ready. I loaded gpu-z, and it showed everything fine. I then upgraded to the most recent drivers for the card off of the EVGA site (177.79) and restarted, and ran 3dmark vantage to get an idea if it did anything. I left the computer while it ran, and came back to a very low score, lower than I've ever gotten by a lot (about 2000 less). The GPU score was really low, and the cpu score was some crazy number about 7x as high as it ever was. I ran gpu-z, and it now showed my core clock and memory clock speeds at 0mhz!! I then rolled back the drivers to the previous one (175..19) to just test if that was the problem, rebooted, and gpu-z, as well as the system scan in 3dmark vantage both show the core clock and memory clock still at 0mhz!! I don't know a lot about video card bios or how to reflash it or anthing, and was wondering if someone could give me some insight on how to fix this problem. Thanks!!!
