Motherboard might be dead - help needed!

post #1 of 4
Thread Starter 
Hi all,
Yesterday, I came home to my family complaining that the family PC wouldn't turn on. Opened it up, tried shorting the mobo power pins to start the PC, no response. Disconnected the PSU from the system (left fans and HDD connected), shorted the green wire on the ATX connector to a black wire, no response. Declared PSU junk, bought a new PSU (Silverstone Strider Plus 600W) today. Hooked up the PSU to the PC, pushed power button, nothing happened (*groan*). Unplugged PSU from mains, removed CMOS battery and left alone for 30min. Reinserted battery, reconnected mains to PSU, push power button, nothing happens (yet more groaning). Shorted mobo power pins, no response. Disconnected PC from PSU, shorted PSU to turn it on, connected fans spun, HDD started up. Reconnected PC to PSU, double checked EVERY power cable, still nothing from the PC.

Has anyone got any ideas on what's wrong? I think it *might* be the motherboard, but I'm not convinced. The motherboard is an ASUS P8Z77-M PRO, BTW.

There are certain things with my own computers that I just leave to "the experts". I have a very reliable computer repair place I take things to that I can't figure out, such as what you describe here. They know me there, know that I know pretty much what I'm doing and thus know that when I bring one of my rigs in that it is a prob beyond me. What you just described is when I'd take my machine into my go-to shop. I'm just saying all this because sometimes that's what ya gotta do. Does your mobo have warranty left on it?

Some PSUs don't play well with some motherboards. Try a different one. Otherwise, old PSU probably killed that motherboard.

Yeah, we only bought the mobo in April last year (not long after Ivy came out)

The only other PSU I have is in my PC, and it's also a Silverstone Strider Plus 600W unit.
