Question: I'm using NVIDIA® AGP card under Windows® Vista™ on my 775Dual-VSTA / 4CoreDual-VSTA / 4CoreDual-SATA2. When I rate the computer's performance, the screen suddenly becomes abnormal. Why?(11/5/2007) Answer: The problem happens with newer NVIDIA® VGA driver version 1xx.xx (i.e. 163.69) Please change your NVIDIA® driver to older version 9x.xx (i.e. 97.19) to solve this problem.
