I just bought and installed a new ASUS M5A 78L-M USB3 motherboard because my old one did not support my new powercolor HD7870 graphics card. Installed my new mother board and now neither of the cards (HD 7870, or old HD 7350) will show anything. The computer turns on and all the fans work, but it loads to the ASUS BIOS options screen, and if nothining is pressed, continues to boot as normal. Once the options screen is gone, the computer either shows a black screen with one white "_" (old 7350), or just a plain black screen (new 7870)
 
Solution
New motherboard + original OS = does not work.
Yeah, that often happens.

Boot from a Linux LiveCD to verify the hardware. If it all works, reinstall the OS.
