It appears I have a dead motherboard in my desktop PC... I never turn it off. CPU is liquid-cooled with an abundance of case fans. Wife was using it last night while I was out watching the Phils game. It's in our bedroom hooked up to the 37" Aquos. I got home around 10:30 and we watched some tv and went to bed. This morning I switched the input on the TV to the HDMI for the PC and the usual black screen, but it didn't wake up when I moved the mouse. Oh shit. I hit the reset button, nothing. I held down the power button and it turned off. Tried to reboot, I get a black screen, a power light on the tower, the lights on my optical drives work, the fans (case, video card, power supply) all work... NO HDD activity light, NO POST.... fuck me. I did the usual troubleshooting, reseated the video card, etc, etc. I pulled the RAM, powered it back on - no beep codes. This fucking sucks.
