Power Supply Troubles - Please Help

post #1 of 3
Thread Starter 
Well firstly, the other I day I was browsing the internet and my PC died on me, the displays turned off and the fans etc continued to run. I powered off the PC by holding in the power button, then tried to turn it back on and it was completely dead. My initial thought was that the OCZ Fatal1ty 550W was dead, then I tried a crappy, spare, "no-name" 500W PSU, without my graphics card plugged in and the CPU fan turned on!

I replaced my PSU with a Seasonic X-Series 760W which I received today, plugged everything in, and got absolutely no response.

I've tried to troubleshoot by unplugging each peripheral (SSD, graphics card, disk drive, HDD) in turn but again I've had no response. The funny thing is, when I plug in the crappy no-name PSU again to just the motherboard connectors, the CPU fan starts running again!

I'm totally clueless now, don't have a clue where to start or what to do. Is my motherboard dead or not?

Check for burn marks on all of the PCBs, specifically near VRMs. Also check for any possible shorts. Try building the PC out of the case and see if that helps.

I thought about the VRMs because my motherboard's are bad especially for overclocking. There doesn't seem to be any burns though assuming that the VRMs are the black squares round the CPU.
