    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.

    Thanks, I appreciate it.

    But, I am running a Q6600 with a Socket 775 G33/ICH9 board. I am hoping to do this without having to do a system reload. That would blow. So, I found a board that should fit the bill. I've replaced boards on more than a few systems in the past and have avoided a system reload by getting a board with the same chipset as the bad board.

    Before I pull the trigger on it, I am going to try a power supply first. I am 99.9% sure it's not the PSU but in fact the motherboard, but I got one downstairs and am going to hook it up and see what happens.

    You may not have to do a complete system reload:
    Contact Microsoft, and tell them that you need to migrate your license to another PC.
    That way, the hash won't get pissed at you for the Mobo/processor change.
    Also, for future reference, Acronis software will allow a restore to a new machine with their version of sysprep.

    It's not that. It's the drivers. Windows won't boot if you have a different hdd controller on the new board, it will BSOD and reboot. Been there, done that.

    Good call, and definately worth a shot before you chalk it up to a bad motherboard. I recently worked on a computer that was doing the same thing - it would turn on, fans would spin, lights on - no POST or video - and it was the PSU.

    Just got home from watching the Eagles game at the bar... I'm pretty fucking buzzed, borderline drunk, but I switched out the PSU and got the same exact result.

    I guess I will be ordering a motherboard.

    if you say it runs 24-7, I say PSU

    motherboards do not just wear out

    but cheap PSUs do

    unless you lost a CPU fan and fried the CPU

    Not a cheap psu... An OCZ 700w modular.

    I got a liquid cooling rig. System should shutdown if it failed.

    OH OK

    that is weird thing to happen

    forgot you said it was liquid cooled in first post

    hope you can still find the same board

    they seem to change out the ones they sell on a monthly basis

    always coming out with something better

    I found a similar-enough board... Same northbridge and southbridge chipsets... Should work.

    I remember when you could simply uninstall everything in Device Manager and then Boot the drive with the new motherboard (or whole a new machine) and then just install the drivers. Was that windows 95 or XP?

    I remember being able to do that back in the day.

    Ordering my new board today... I'll post a link to it when I get home.

    Late to the party here, but I had the same issues about a year ago and it was actually the video card that was bad. Machine powered up but no video signal and no post. Apparently the bad card kept the machine from posting. If you have a spare card laying around give that a try too before swapping the whole board.

    I tried that... I actually pulled the card, cleared the CMOS and tried to use the onboard video, no change.

    FUCK!

    It's not the motherboard.

    I got the new board today and put it all together and it's doing the same motherfucking thing.

    I tried a different PSU before ordering the board. I tried a different video card.

    Now I got a different board, symptoms are still the same.

    I am inclined to think my processor died. I am going to try different RAM for shits and giggles, but I am pretty sure it's not that.

    I think I have some kind of core duo processor downstairs in my parts stock for work. I might give it a try tomorrow.

    besides the RAM, not much left to be

    CPU failures are rare as you probably know. Its the unlucky lottery of computer problems.

    Intel 775 chip - 3 year warranty, right?

    Tried different RAM, tried different CPU.

    I am stumped.

    This is insane.

    I am going to try a 2nd different PSU. I tried a spare PSU I had here that is brand new, but I never tested it.

    I am gonna yank the PSU out of my stepson's rig because I know it works.

    4-pin CPU power plugged in?

    can you try to setup everything outside of the case? maybe its grounding out

    Yeah, the 4-pin is connected. I am gonna try this other PSU tomorrow. I am done fucking with it today.
