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?
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.
