Power supply was working, put computer to sleep, power supply went dead. New power supply was working, did not put computer to sleep, power supply went dead. Is the problem two faulty power supplies or a motherboard from hell?
Over the past week I've run into a problem with a couple of power supply units, or potentially the motherboard. The best way to describe this problem is to describe the chain of events in order:
- Computer is functioning normally for years. I put the computer into sleep mode and go to bed.
- The next morning the computer will not power on.
- The power supply, NZXT HALE90, makes it's usual "click" sound, but no power.
- There is also no power when attempting to power on through the motherboard's power button.
- The motherboard LED light does go on when the power supply is switched to "on".
- The power supply is removed, tested with multimeter/paperclip trick: No power.
- A new power supply is purchased, a Corsair gold-rated unit.
- The power supply is connected to the computer. It powers on successfully and the computer works.
- The power supply had something like a "hiccup" when powering on. Powered on, then off, then on again.
- This also happened to my first power supply (HALE90) the first few times using it back in 2013.
- Computer continues to function normally for the next couple hours. No problems to report during usage.
- I fall asleep with the computer still on. Upon waking up, the computer is now off. The monitor is still on.
- The computer will not turn on. The fan will spin for half a second, but no power.
- As before, the motherboard LED goes on when the power supply is switched to "on".
- The power supply is removed, tested with multimeter/paperclip trick: Power cuts within half a second.
And that's where I am right now.
I didn't find the right solution from the internet.
