re: #7 Great White Snark

Fans, DVD, board telltale lights all good. Corsair water cooler running. Rechecked jumper that configures for processor.

Double-check and reseat your expansion cards (particularly the video card), the RAM, and all of your cable connections.

As far as a CPU jumper, I haven’t seen a mobo with something like that in a long time; what board is it?
