I have an Nvidia GeForce 6200 AGP card and I play DOD Source and HL2 games and my games freeze with looping sounds. I have updated all of my drivers and all my settings are at recommended and on 800x600. I get a steady 60fps but my games always crash!!
Does it crash while doing anything else or just playing DoD Source and HL2?
Just when playing Source games.
Are your drivers up to date?
Yeah, everything is.
Maybe your sound card. Disable the sound in the game options and play for a while and see if it crashes.
I tried that and it still does
Virus Scan? Tried re-install?
I have a 6200 and it doesnt crash for me. Get a new card they are like $50 dollars for a 7 series.
