This has pissed me off beyond ALL words. Here is the problem, plain and simple:
I had a Gigabyte GA-EP45-DS3R that was giving me trouble, would shut down randomly and would do the dreaded Gigabyte mobo reboot 'loop' on a cold boot. I chalked this up to immature BIOS, or maybe just the newest F7a BIOS was bad, so I tried a Biostar I45, which I've heard nothing but good things about. Mind you, I have an HD4870 on watercooling that I'm running. I switched out to the Biostar mobo, brand new, and hit the onboard power button. Lights come on, fans spin, hard drives are going, and I can see the LED post codes on the board, but NOTHING comes on the monitor, JUST like with the Gigabyte mobo.
I didn't have any mouse/keyboard plugged in, so the post codes kept going up until the CPU temperature was being displayed (which is normal). It reads around 20C, which I know is wrong, but whatever. When I plugged in a PS/2 mouse and keyboard, the post code hung on 2E, which means "initializing all output devices" according to the manual.
Also note, when the computer boots, my HD4870's LEDs are lit up (from the left, looking straight at the card, vertically) on LED #1, #2, and #4. Any idea if this means my video card is bad? Could it be my DVI cable? I've tried the monitor on my server with a VGA cable and it works, so it's not the monitor.
My PSU is also new--Corsair TX750. I'm out of ideas, guys. Could my CPU be bad? Would the board even POST with a bad CPU?
Thanks.
