Recently I have been experiencing frequent crashes in-game followed by 5-10 seconds of hang time. When I first built my PC last Christmas I would never have one, but in the last month or two it is almost every time I play. I posted the kinds of errors I get in the picture below. If I don't crash I usually get artifacts in game, distorted and glitched images, instead. I believe it is caused by either my Memory (1GB Corsair PC-5300 (667Mhz) Value RAM) or my video card ( Evga, Nvidia GeForce 8400 GS 256Mb) I temporarily had access to 2GB more PC-5300 but it was from a different brand not Corsair, but I thought what the hell and put it in with my other RAM while I had them. I no longer do and am back to my 1GB Corsair PC-5300 (667Mhz) Value RAM. I did try to overclock my video card but not with the intention to keep it over clocked, just to see what performance it could achieve. I did both of these things around the same time so I don't know when it started. It could be drivers or other settings in Windows XP but I doubt it because I just reformatted a few days ago and still crash just as much as I did before reformatting. My guess is the memory but I'm not 100% sure. Any Ideas what I should do first? Maybe I'll do a stress test.
