I've been using hibernation instead of shutting down on my computer for some time (about a year) now and it didn't give me any problems, however, recently, I put my PC to hibernate and when I pressed the keyboard to restart it, it wouldn't even power on. I tried using the power button but it didn't power. The thing is, I tried unplugging the PSU, all components but the CPU, power button and 24 pin-cables and the computer still won't start. When I say so, I mean that the LED indicating the computer is receiving energy lights up, but when I press the power button there's no response, even the fans won't spin or anything.

I changed the PSU for a new one and nothing happened, however, I replugged the old PSU and after letting it gather some dust for the night, I plugged it back and tried turning it on and it did so. The computer ran fine and hibernated with no problems every night through a whole week. Then I hibernated it for a whole weekend and try starting it over once I return and it won't restart. Swapped with the new PSU and still nothing.

Afterwards I took it to the technician and after changing the RAM it would power on fine over there, but no response once I plugged it at home, even after unplugging it for the night. I took it to the technician again and it started just fine over there. I was told it could be the energy over at my house, however, it used to start up just fine before and my other computers in the house start up just fine (yeah, I did test the PC on different plugs around the house too). Finally, two nights ago I decided to plug it on and tried starting it and nothing. I left it plugged on for five minutes and then pressed the start button again and it started up! Then I put it into hibernation that night and it booted up the next morning just fine.

So, according to my technician, it should be the energy over at my house, according to my father, it should be the MoBo's frequency. He also suggested that making the computer hibernate rather than fully shutting it down might have done something to the BIOS/damaged the motherboard (which I doubt) so what would be the most likely cause of this problem (I'm a bit wary of making my PC hibernate now, and my father suggested shutting it down normally from now on instead, but I'm still worried that it might not wake up either, so I'm placing it on Sleep only from now on) so I can fix it for good.

Also, in my Power Settings, I made it so the power button was set to put the computer to hibernate, in case that may cause problems. Finally, in case you may ask, I did try shorting the power pins and it did nothing.

Causes I can think of are:
1. Corrupted Hiberfil.sys file... this is where the hibernation, sleep, standby data is stored and in my experience is the main cause of Power Saving related startup problems. To try solving it; Switch the Power Options (in Control Panel) to no hibernation, sleep or standby or create a new power plan selecting Never in all settings... next save the power plan with a new name (EG: "Always On") and Apply it. This will delete the Hiberfil.sys file and rebuild it new the next time you restart the computer and enable any of the power saving plans.

2. The BIOS settings if corrupted can cause different startup problems.. reset it to delete any corrupted data.

3. To many Temp files. Going into any of the different power saving options includes saving the data in the temp files being used, and if these files are large in size or number, the data contained in them is saved in the Hiberfil.sys file so it's best to regularly delete these files to lighten the load on the Hiberfil file and lessen the chances of power saving and performance problems. To delete temp files; Start button > Select the Search bar or click on Run and type "%temp%" and delete the account temp files and next type "temp" and delete the system temp files. Or use CCleaner to delete these files.

4. If you encounter the problem again, try loging in Safe Mode or Last Known Good Configuration and reset the Power Options to use the new Power Plan, and apply suggestions #2 and #3.
