A few weeks ago I began to notice a decline in performance from my PC. It started with CoD:MW2 freezing randomly forcing me to hard reset several times. This Issue also started happening in Left 4 Dead 2. I tried some older games and noticed a significant increase in the amount of stuttering and some substantial framerate drops. Left 4 Dead 2 became unplayable because the frequent freezing and crashing. I tried several different driver versions including the 191 drivers, the 195 beta drivers and the 195 release drivers.
I was running the windows 7 RC but after these problems started I decided to do a clean install of Vista. Unfortunately this made things worse, WAY WORSE. Now not only was it freezing up in games it also started happening on the desktop. One program would stop responding then another then windows would become totally non-responsive eventually crashing to a black screen. A few times it managed to recover from this the others it blue screened or required a hard reset to get rid of. This occurred on the first boot with no driver installed and continued to occur after installing the 195.62 drivers.
I was starting to think that this may have been a CPU issue until today when I loaded up Unreal tournament 3 and the screen flooded with artifacts after about 30 minutes and then froze until I hard reset again. After I rebooted everything seemed fine so I tried UT3 again and the same thing happened after about 3 minutes. I reboot again and leave because by this point I am really frustrated. I come back 45 minutes later to find that the desktop was covered with artifacting and was totally non-responsive. I rebooted and it happened again after a few minutes.
I don't know what to do I've been searching google and forums and have come up with very few solutions none of which corrected any of the problems. I need to know whether this is a hardware issue or if there is anything I can try to fix it. If it is a hardware issue is it an issue with the graphics card or could it be something else? If the graphics card is bad I guess I know what I'm getting myself for Christmas.
If you need any other information let me know. Thanks in advance for any help.
