I have been having an issue with this graphics card I am using, something I have never came across before. This card (Nvidia 8600GT) used to work but randomly started doing this. I have tried this card in multiple machines since but I still get the same problem. I have a dual DVI graphics card and I can't get either DVI to work UNLESS I am using a DVI to VGA ADAPTER. Once I have a VGA connection up it WORKS as if there is nothing wrong. I have tried multiple monitors/TV's to diagnose this. Does anyone have any ideas? I've CHANGED setting in the BIOS the graphics card is set as default.

(The onboard card on this MOBO has been acting up too, weird graphical glitches on the screen when there are a lot of images)

If there is more info needed I will post a .NFO
