Gonna make a backup image of system and try 32bit and see how it goes will post outcome

Did you double check to get the 64-bit drivers, not 32-bit? You should also reboot after installation.

Becuase you had BSODs system surly has been generated dump files.Find all *.dmp files in C:\Windows\Minidump pack them and attache to post

lecture:Crash Dumps - Analyse Bugcheck and Process

of course i checked, sometimes during installation it will BSOD sometimes its after the reboot but its definately when i install the NVIDIA 64bit drivers

Does your monitor have the x64 driver/profile as well?

Have you uninstalled the installed drivers before installing the new one? What about the PhysX drivers, did you uninstalled this as well?

When you install the drivers, do you do so with Higher Privileges? (Right Click on file and "Run as Administrator?")

I have found that uninstalling both the driver and physX helps me tremendously.

uninstalling old drivers has not been the issue since i have been trying to get this running from a fresh vista install still with no luck
