So my pc went to sleep earlier and may have slipped into a coma, now I'm not getting any power to the system. I swapped a new psu in last weekend, so j figured that may have been the culprit. I unplugged the 24 pin and cpu cable and plugged my old psu into with no change. Checked the fuse and the outlet I'm using and they're both fine.
Any suggestions?
I don't have a voltmeter unfortunately. I've tried the case power button initially and the built in power button on the mobo. Neither have worked. And the built in one should be lit even if it's powered off. As long as it's receiving power.
Yes, if it has an internal one that should light up and work.
You can try unplugging components and see if anyone of those shorts, if not it might get expensive.
I haven't removed anything, but I unplugged it all and hooked up my old psu, only to connecting it to the 24pin mobo and 8 pin cpu. Still nothing.
With a voltmeter you should be able to see some power on the board in all sleep stages, question is where. A stupid thing which sometimes breaks is the power button, so try shorting those two pins.
