I also have the same problem with the 6200oc. My comp would reset when starting up CS-source and DOD source. Its the vid cards fault and only the cards. I installed the update from nvidia and CS-S runs fine now, but my CS-1.6 and Guild wars now have problems and crash. So if i want to play cs-source i update to newest driver. If i want to play cs-1.6 or guild wars, i uninstall new driver, and install old driver that came with video card. Also this vid card blows, half my other games that worked on my 8 meg vid card i got with my computer in 1999, have graphic problems with my new 6200 card. In Janes USAF a flight sim, my sky is all messed up. In AVP2 the charaters in the game shutter, in Nascar 2002 the car shutters. Again all these games worked fine, just lagged a little with my original 8 meg vid card. WTF i cant bring my 6200oc back cause i bought it in July and it can only be brought back with in 21 days. I am calling nvidia and compaining. I hate this waste of money.
