Okay, so this is a custom-built machine that hasn't had any trouble until now. System specifications are:
Gigabyte MA790GPT-UD3H Mobo
AMD Phenom II X4 955 @ Stock; Arctic Cooling 64 cooler
4gb G. Skill
550w OCZ Fatality PSU
And when the problem occurred I was running 2x Radeon 5770 (one Sapphire, one XFX) in crossfire
Anyway, I was using the computer leisurely for gaming (SC2) as I do quite often and randomly the display shut down abruptly. I thought maybe it was just a random quirk of the machine (this hasn't happened before) but found that a hard-reset (4s on power) wasn't shutting down the machine. Anyways, after deliberating I cut power and attempted to restart.
Anyway, the machine now won't post, the display doesn't turn on, and there are no mobo beeps. What is peculiar, however, is that the GPU fan is immediately set to full speed. I have attempted to swap out the GPU for the other one, thinking that maybe it had met its maker, but it does the same thing.
Anyway, I've tried both GPU and even tried the onboard video, but nothing is giving me any display. My first impulse is that maybe my motherboard gave out, but I don't know how to test this since I don't have any extra mobo laying around. There are no beeps from the mobo, although I haven't specifically added an onboard speaker.
While I put this machine together, I'm pretty ignorant when it comes to troubleshooting things, so I appreciate any help or insight.
