I just built a new computer and it runs great on intel integrated graphics. However, as soon as I install my 680 (ASUS brand), I get no signal to the monitor. I can hear it boot to the windows desktop, but nothing shows up on screen. Mind you, I haven't installed the driver yet and I'm still using the blue VGA for integrated. With this card installed just into the PCI slot, I don't see POST, BIOS, or Windows.

If I take it back out, it fires up properly. Anyone have any idea whats going on here?
