I've been having this problem lately, which causes games to crash (stop responding). Basically while gaming the everything sometimes just freezes up and I hear a kinda weird sound, and I get a "stopped responding" window. Not that annoying though, since it hasn't occurred much really, but would like to get rid of the problem
By the way, this problem might have nothing to do with graphic cards, but I just suspected the gpu could be the cause. I just got my old graphic card replaced because I had the infamous "gray screen of death", so I hope it's not a gpu problem again...
Anyways, this has seemed to be occurring in quite a few games, the ones that come to my mind now are NBA 2k10, Just Cause 2 and in the recently released Mafia 2 demo. In the Mafia 2 demo it occurred just under 10 minutes of gameplay. I ran the benchmark before playing though. One more thing, after the crashes, it seemed like pictures on websites and stuff had weird colours all over them, making it hard to see what was on the pictures. And one time the sound was all weird after a crash, making some weird "crackly" sounds.
Might also mention that my cpu is slightly overclocked, with no voltage increases, and my gpu is factory overclocked.
Here are the specs
In this case, Possibly a operating system or game problem, The game may have not installed properly, or something importants missing from your operating system, or both. I usually refresh my operating system atleast every 6 months, yours may be due?
To maverick; try totally removing the audigy from your system; sounds like Creative SCP, but I've seen these type of crashes happen for other reasons...(such as my 790i, but I know thats a motherboard problem...). Could be PSU related as well.
I still have this problem, and have got it in MAFIA 2 demo, MAFIA 2 full, Medal of honor open beta and NBA2K10. Seriously, what is the problem, is my graphic card defect? I'm gonna try reformatting soon
