Hello, I am trying to use my new Radeon HD 6850, but I am not getting any display when I set the default Graphics to PCI-Express. I am sure that I am plugging my monitor into the graphics card, although I had to get a DVI-VGA adapter because my monitor is VGA, but the graphics card is DVI. The desktop curently has a Leonite2 (P5LP-LE) motherboard, with 2 GB of RAM, and an Intel Core 2 Duo proccessor at 2.00 GHz. What is the problem? I will check my PSU right now.
