PC not restarting unless cut the power for about 10 minutes.

[sdw123]

Hi, I'm so confused about this situation. My PC can't power on again or restart from OS after shutting down. But power on normally if I cut the power from the wall and keep 10 minutes.

 

I used another motherboard. but same result. I'm using Seasonic X650 . So not sure it's a PS fault. Any solution than replacing the PCU.

Do you have anything overclocked?

VGA is overclocked. But same results even using onboard gpu.

Does your PSU Fan work? I could be tripping a thermal limit.

Yes. I don't think it related with temperature. Even I powered on after many hours and just turned off , same results. And no any difference even worked 24 hours.

i don't want to be dense about this, but are you SURE it's not a thermal issue? 
I ask because the 10 min. downtime is weird and sounds a lot like a cool-down time...

How about the cpu cooler? is it working OK? Did you replace the thermal paste when you switched MoBos?

What does that mean?

By restarting, shutdown or turn off using power switch, I can't power on again unless cut the power from the wall and keep for about 10 minutes.

Yh. cuz

1) doesn't matter I restart or shutdown early in the morning for the first time of the day or after an 8 hour nonstop render problem is the same.

2) Can't power the pc even I stay hours, IF I didn't turn off the power from the wall.  ( so at this stage pc is turned off. But power keeps coming to the powersupply.

 

also yp. I reapplied thermal paste and cpu/gpu tempreture neven go over over 50C (122F) .

wait... so, no matter the time or if you used or not the pc before the same day, BEFORE being able to turn the pc on you need to UNPLUG the PSU from the wall for at least 10 min (give or take) am i correct?

exactly.

you know, my dad's car had an issue quite like this, you had to put it in "contact" and wait for EXACTLY one minute before you could start the engine. 
It turned out to be an electrical problem. So, while i'm not saying it is THE SAME since we're talking pcs and not cars, it does sound oddly similar. My money is on faulty PSU, not thermals but circuit wise. Do you have a spare PSU to check this?

Sadly no. I'm also guessing it's an electrical problem. I'm affraid of buying a new PSU since in here 

 some says they replaced mb and psu , but still having the issue.

Why can't you? What's stopping you? Do you get electrocuted? We need details.

What happens when you press the button? Does it not turn on? Does it turn on and immediately off? Does a motherboard show an error code? Have you made any hardware changes besides testing different board?

Nothing happens after pressing the power button. No. Already changed motherboard and graphic cards.  This must be a similar situation.

I know this is probably wrong, but try taking the CMOS battery out for 5-10 min

Already tried that.  But thanks anyway.
