So this is not a new build, I built this machine around February of 2011 and tried a fresh Windows 7 64-bit install the other day.
Everything about this build was fine from the first install of Windows. The other day I tried installing Windows 7 64-bit again and while it was doing its own thing I went to take a shower to come back to a computer with just a blank screen and no boot. I had DVI plugged to my GPU so I moved that to the motherboard output.
I get no boot from disk, hdd, or ssd. No BIOS or anything from display, my monitor goes from "no signal" to just standby. I have tried DVI, VGA, and HDMI and 2 different monitors just to be sure.
All motherboard LED's seem to light up for their test but "boot_device_led" appears to stay lit constantly without turning off (it is hidden behind one of my GPU's but it's on)
I have reset CMOS according to the motherboards manual, moving the jumper from 1-2 pin to 2-3 for awhile then moving it back, to no success.
I took everything apart, double checked all connections and everything seemed fine, it wasn't a new build and had just been working for well over a year with no problems until now doing a fresh Windows 7 install. All fans spin up, all gpu, cpu, psu, and case fans.
Any ideas? Thanks.
