Help, what have I done?

[jkohm]

I replaced my cpu, powered the system up, The bios reported finding a new cpu and asked me to review the settings. I noticed one of the hard drives was missing from the setup. The HD power cable had come lose. At that point I think I did something stupid. Instead of exiting the bios setup I powered off the system with the power switch and connected the HD power cable, then powered on the system. Fans come on, standby power led on, no beeps, no display. What can I do now?

Hardware: Asus P5Q Pro MB, Asus eah4850/hdt/ video, Q9550 cpu, 2 - WD Caviar SE16 sata300 500gb HDs, 8gig OCZ Platinum DDR2 memory.

Try reseting the bios,might help.

nah you didnt do anything wrong.
you could have corrupted the bios though.
worst case would be a totally wiped bios in which case you need to hotflash or RMA the baord.

i have powered off from the bios many times and never had an issue.

use the reset cmos jumper on the board and reset the unit, see what happens.
(power off the system, move the jumper for 30 seconds, then move it back, then power on your system)
