I am having a strange problem on my rig, that I believe is a PSU issue, but I wanted to see if anyone here disagreed and thought it might a MB issue.
My system runs fine, no crashes. The problems all have to do with boot up and shut down:
1. Occasionally when I try to start the system, I get no response at all. No fan, no led, nothing. when this happens, i usually have to shut the PSU's power off (at the rocker switch), and wait for more than 30 minutes before trying again. I can always get it to start eventually, but it always takes a lot of switching the PSU on and off. The other strange thing about it is that when I turn the PSU OFF, after ~5 seconds the power LED on the case flickers; sort of like a capacitor is discharging.
2. Frequently on shutdown, Windows will go through its normal shutdown operations, but instead of the system turning off, the case lights and fans will continue to run (I suspect that everything is still powered on, but I can't tell since the OS is shutdown).
