Monitor won't display after trying to install new GPU.

[Jacobslap]

Tried installing GTX before 550 ti from my Crossfire HD 6850's. When I first installed the 550, the monitor received no signal and I realized I didn't uninstall old AMD drivers... So I put the old cards back in, power and bridge connected, start up the computer and the same thing. No signal. I can't try motherboard display because it uses some wield slot I don't have a cord for. Please help meh!

Fixed by removing jumper pin peice, starting computer, turning it back off and putting the piece back in to reboot bios or w/e.
