Hi all, I have a Biostar TA690G AM2 motherboard and a geforce gts 450 graphics card.

My problem is that the computer has a question mark next to the graphics card in device manager. And my computer won't recognise my lg monitor. Before I had no problems and was able to view at 1680x1050 and my graphics card and monitor had no problems. I have reinstalled windows 7 64 and installed all drivers for graphics card and reset the bios! Nothing so far is working and I'm getting frustrated. Maybe it's a bios thing but I have tried turning off. On board graphics and still it won't detect them.

Any help would be great

how are you installing the NVidia driver ??? looks like its working fine on the generic vga driver built in to windows seeing your able to go to desktop and do some looking around ...

Hi, I finally worked it out after looking at all system specs etc. windows still had an old 32bit driver somewhere and that was causing all the bother.
