I have a custom built computer.Asus p5n-d motherboard,4 GB ram with Vista Home Premium 64 bit.I installed a Geforce 9800 GTX+ and after installing the drivers the pc gets a blue screen when I boot into windows.I can't tell what error code code it is since it is too fast to see anything.I installed new drivers but Vista still doesn't boot.It takes on the black screen with a cursor.You can move the cursor but it stays like that forever.Any suggestions to how to fix this problem will be appreciated.Thanks
