Help! Can't boot with any graphics card but a 7800GT!

[MindoverMaster]

Well a new PSU (650w) didn't work. My only conclusion it is my motherboard just doesn't like PCIe 2.0 cards. It worked with the 8800gt for a while but whatever circuit enabled backwards compatibility has went bad. The 7800GT is a PCIe 1.0 card which is why it works flawlessly. I guess ill be building a new rig sooner rather than later.

650, Slay. As of type, yes, we need that information.
