Well.. this sucks.

System specs:

Gigabyte GA-Z87X-D3H mobo
i5 4670k CPU
8GB DDR GSKILL memory
Geforce 760

anyway, I had been running the system a little over a month and everything was fine. I decided to make the jump to windows 8.1 from windows 7. Did a fresh install of windows 8.1, but noticed there was the little message in the bottom corner of the screen "secure boot not configured correctly". Did some googling and there was a few recommended ways of enabling it. Went into the bios, enabled secure boot and saved the settings and rebooted. System sat there with no monitor signal and would not post.. nothing is happening. Rebooted it, same thing. I cleared the CMOS.. same thing. Pulled the battery and waited 15 minutes - system comes on for about 5 seconds, turns off, and then comes back on and nothing happens - fans are running but no signal to the monitor and keyboard wont light up - its not posting.

I've cleared the CMOS a bunch of times, i've unplugged everything besides the monitor, pulled all the SATA drives, unplugged the video card and tried the integrated HD intel one - no go. I found this thread:

This guy had the exact same issue and could not ever get it working again.. I dont understand how clearing the CMOS is not fixing the issue. Any ideas?

Did you remove your video card when trying the onboard video?

Do you have a speaker plugged into the board?

Is there a switch on the board to change from the main bios to the backup?
