Build from 2009ish has stopped working while I was asleep.

The last time I had that happen the PSU took a dump on me. It was also a socket 1366 system.   I started having intermittent posting problems then one day it would not post period.  Lights on but nobody home. Hooked up my backup cheapy PSU and she fired right up. PSU tester said the PSU was fine, go figure!  A MM is not going to get you the result you need for testing. 

+1, you can't really test idle and load voltages if the sucker won't even run.

 

I remember when my silencer first gave up the ghost, it was all funky and then poof, wouldn't start. I sent the board off to Gigabyte thinking that was it, nope. Luckily I was building a gaming computer for my cousin and tried her PSU...presto. Perfect working machine, sorry Gigabyte

 

I was ready to rebuild the rig since it was well worn but decided to test the PSU and it came back to life!
