Title says it all. So I NEVER put my PC to sleep usually since I have an SSD and it boots so fast that there's usually no need to do so, but I tried to put it to sleep on my way to class once and it did not want to power back up. It got to the point where I removed parts from my PC trying to start up and it still wouldn't load. It eventually (and I kid you not) powered itself back on after an hour of never touching it, and the PC loaded back right where I left off with no errors. This only started happening after I installed my new PC case and liquid cooling system.

The second time this happened yesterday, I did a bit of some research and figured out a way to get it out of sleep mode which I tested and worked twice. How I fixed it:
1. Unplug the PC from the main and power off power supply.
2. Hold down the power button with PC unplugged for 30 seconds.
3. Leave PC alone for 3 minutes.
4. Replug everything back in and it powers back up right where it left off.

Research tells me it's that my USB devices need to be enabled to wake the computer up from device manager but I have already done this and checked it 3 times. Any ideas to figure out why my PC does not want to come out of sleep mode the normal way? I have no idea. Any suggestions are greatly appreciated.

Since resetting the power supply unit makes it work then that would usually indicate that a protection circuit in the power supply unit has been triggered when the system entered sleep mode.

Try troubleshooting with a better quality power supply unit.
