Vista says: "This problem was caused by NVIDIA Graphics Driver. This program was created by NVIDIA Corporation. NVIDIA Corporation does not currently have a solution for the problem that you reported."

I have re-installed the drivers still no luck.. The driver wasthe XPversion..I tried installing the vista one from the site but it doesnt think my computer is running vista.. Maybe i need to just re-install windows..
