Vista - Driver Error

Hello all,

I just got my pc a week ago. If i am playing a game, lets say Crysis and all of the sudden the screen goes black but i still hear sounds. it then goes to the blue screen of death ( it goes to quick to see what it says but i see the words nvlddmkm.sys) , reboots and says my nivida driver stopped working or does not rebot but isntead it says nvlddmkm.sys has stopped responding and has recovered. Any help would be great. AT First i though it was a bad graphics card but i took my GTX 285 back and got a new one and still the same problem. any suggestions on how to fix this annoying problem??

my pc is:
windows vista ulimtae 64bit
intel 1.7 2.66ghz
patriot viper series tri channel dd R3 pc3-12800 6gb 1600mhz low latency dimm
BFG gtx 285 OCX
gigabytet ga-ex58- ds4
corsair TX series CMPSU-850TX 850 W

Thanks

First thing that comes to mind is, are you running the latest driver?

GeForce Release 182

Yep i have the latest drivers from Nivida.

Also my motherboard bois is up to date.

Thanks though
