Hubby's is having a problem with his new desktop computer. When there is a power outage or he unplugs the power cord from the wall, sometimes it will not turn back on again after plugging it back in. No fans, lights or anything. It has happened twice now in 2 months. First time it was after a power outage (not a surge) and he pretty much disassembled the whole thing trying to figure out the problem. Made sure it wasn't switched off in the back. Tried a different power cord, removing ram sticks, switching the power button with the reset button. Tested with an old 500W PSU that he wasn't sure if it was even strong enough (or even worked) and nothing. Then he put everything back together in it's original state and it worked! No idea why it stopped or started working again. This was about 2 months ago.
Fast forward to today. We had a thunderstorm and he unplugged his computer from the wall, after turning it off. And it happened again. No light, fans or any kind of response after he plugged it back in. He again made sure it's not set to off in the back but that is about as far as he has gotten. He obviously does not want to have to possibly tear his computer apart every time there is a power outage or he unplugs it. IF that would even work again.
What might the problem be? Is there some easy way to check when it wont even turn on right now? Could the culprit be some very stupid bios setting or is hardware failure more likely? Any suggestion for how to get it to turn back on without picking it apart and putting it back together? Any ideas?
This is his computer. Most of it is new except for the case, the 240GB SSD and the PSU which are maybe 5 years old: Hubby's computer on PCPartPicker
