Okie dokie, so this is a hand-me-down system that I had given to my brother a couple years back. Old C2D E6600, 2 gigs of DDR2-800, 320GB HDD, and a XFX 6770. It's being powered by a Corsair HX620. I built the system back in late '07 if I remember correctly, with everything being the same except for the GPU and a DVD drive. So enough about the system, here's the story / issue.
My brother comes home from his buddies house to see the computer powered down, tries to turn it on, and nothing happens. Hits me up, and I go to check it out. Here's a list of things I've tried.
I pulled everything but 1 stick of ram, and the processor. Still doesn't turn on. No lights, no post, NOTHING at all.
I disconnect the PSU from everything and use the paperclip test, which the PSU comes right to life.
I pull everything out of the case, thinking there could be a short somewhere, and try with 1 stick of ram, and the processor. Still nothing.
I grab a known working spare PSU to make damn sure it's not the PSU (a paperclip never told anyone anything about voltages being within spec), still nothing.
The last thing I tried was jumping the PSU while it was connected to the mobo, to which everything turned on, but there was no display on the monitor, no beeping from the mobo (post or error), nothing at all. Just lights and spinning CPU fans.
So, as a last ditch effort, I'm popping on here for any ideas. I'm guessing the mobo went, but there aren't any visual signs to point to it (no bulging/leaking caps, no scorching, etc). The CPU was ALWAYS kept cool (sub 40c under load), so I don't think it would fail out of nowhere like that.
So fellow [H] members, do you agree that the likely culprit is the mobo, or do you have any other troubleshooting ideas for me?
