MSI M5A78L-M LX Plus
Download this manual and look at page 2-14. Also, be sure to plug you monitor into the video card, not the onboard connecter.http://www.microcenter.com/images/shared/products/customercare/083790/E6524_M5A78L-MLX_Manual.pdf
Somehow the 6 pin plug that goes into the graphics card fell out. I guess that I didn't push it in all the way. After I plugged that in I changed the setting in BIOS to GPX0 and it now works. Thanks!
