display driver stopped working?

hi guys,when i overclock my graphics card 700/1660/1000 it will run but after a while of crysis or even 3dmark06 it will stop the program and say display driver has stopped workin,i run riva in background so i can monitor temps and they peak at 72c fans at 100% so its not a heat issue,any idea guys?....edit...it dont cause any probs,after i close the program crysis etc its back to normal.

nothing to do with vista 64 bit, ive had it on vista 32 bit and on other forums tons of ppl have had the error on 64 bit and 32 bit vista and 99% of them have all oveclocked there video cards

yeah im using vista 32bit with latest beta drivers.so its not that ive reached the max i can oc my card then?in theory it will go more right?
