my win vista 32 bit all-in-one Computer crashed, , went to sony, downloaded all new drivers, including avermedia tuner driver, computer has two hard drives labeled HD 0 and HD 1 one was empty so i jammed win 7 ultimate 64 bit, was able to restore screen and system but nvidia 8400 graphic card is not working properly, cannot download new drivers because it says not compatible because win 7 is 64 bit, system is running great, except for graphics memory which states none, even though I have a great picture. Cannot get in to HD 0 which is vista 32 bit in safe mode, did a clean install of vista on HD 0, now cannot get back into safe mode to install drivers, need to make HD 1 work properly.
How can I get the graphics card working properly on HD 1
