OK i have officially given up with the NVIDIA 162.22 driver and am now going to sit back and await the new drivers to come out!
The registry tweek i came across made no massive difference. Even though i have maintained longer periods of stability, im still getting the usual crash ecentually, again this has ranged between 10minutes to 5 hours of use of the system!
And whats worse is Bioshock is released next week and im on pre-order 
shame the PCs not going to be fully up to running it!!
