Ok so I thought I fixed this problem but apparently it's back. I'm willing to try the stuff Kong suggested in the post right above this one but it's so random I don't know how to. I infrequently get very random blue screens and there seems to be no pattern. The majority of the time it happens not long after I start up my PC. It gets to the desktop and everything seems to load fine and then it just crashes without me doing anything. Once in a blue moon it crashes during a game but it's so infrequently it doesn't seem to be related to the game running. I'm also getting sound issues rarely when I play games that make my PC run harder. It sounds like the whole PC is lagging and making the sound play in slow mo.

So any ideas on how to stress test my PC in safe mode besides just repeatedly rebooting it?

I heard some PCs can reinstall windows without an installation CD, how would I check for that? I don't know what happened to my installation disc but it might be buried somewhere.

I think all my problems are caused by my graphics card. I checked and it seems like my warranty ran out and it's a weak card anyways so I'm thinking of buying a new one. Can you guys give me suggestions on a decent card that will last a while and doesn't cost that much?

Thanks for any help.
