Been having some problems with my PC. First my keyboard was acting a little weird. Random disconnects. As part of the troubleshooting process I uninstalled a number of USB ports, trying to figure out if it had anything to do with their drivers. So, I turned off my PC and wanted to start it up again to get it to reinitialize those USB ports.
Except I couldn't get my PC to boot up anymore. That's the first time I noticed this behavior. It didn't even post. I hear a click, my GPU's logo flashes briefly, the fans begin spinning, and then everything turns off. Light on the motherboard's power button is on. The error display is off though, so no idea what's happening there. The light on my case's power button is on as if the PC itself is also on. Holding down the power button until it turns off and then trying again sometimes works. But usually only power cycling does the trick. Even then, it's not guaranteed.
Strangely, it only does this from a cold boot or when trying to wake from sleep. If I restart my PC, it will just restart properly every time. I'm getting the feeling it might be my PSU? I don't know.
I checked my motherboard and it seems clean. No leaky capacitors or whatever. Memory is properly seated. Doubled checked the power cable from my PSU to my motherboard. Seems fine?
If anyone's got ideas on how to diagnose this, I'd be super thankful.
What motherboard/cpu?
