Motherboard Haunted? (Super natural activity!)

[K1LLA_KING_KONG]

Hopefully the title got your attention. Obviously I'm not serious but there is no logic with my problem so that can only points towards a mysterious entity within my mobo

 

Problem: If I shut down my Pc overnight or for some long period of time. It will not turn on again

 

If I turn it off briefly, it will boot again if without issue. 

 

I have bridged the pins on the 24 pin connector and confirm the PSU is supplying power. 

 

The only way I get get it to turn on is not based on any logic, connections, electronic components. It based on random luck without any input from myself. 

 

I will attempt to turn it on numerous times, just mashing the power button. Nothing happens, I try again 10 minutes later, an hour later, 2 hours later. Nothing! 

 

Then when I'm not even in the same room as the pc, it will boot by itself!

 

also take note I have confirmed the problem is not the switch itself. (I have also bridged these pins to confirm it will not start like that that)

 

PC:

Asus Prime X470 Pro

Ryzen 3700X

G Skill 32GB 3600Mhz

2070 Super

Samsung Evo 1TB SSD

 

I have tried everything, full disassemble, reassemble with only the basic hardware, confirm connections, test power on main cables. But what is comes down to is the mobo will not boot until a random time that it feels like it. My only idea could be something to do with a capacitor, perhaps not charged enough? who knows. 

 

I don't want to buy a new motherboard as it works perfectly when it's turned on. I just don't turn it off anymore. but sometimes it just happens and I can't use my PC

 

What would the next point to troubleshoot, test with multi meter? 

 

Any real advice would be greatly appreciated. TIA

This may be a stupid question, but how sure are you that you're bridging the right pins?

BIOS update? You sure the power button is plugged into the correct header pins?

For the 24 pin connector, bridge pin 4&5 your fans turn on. (on my pc) 

 

For Power switch pins its written PWR_SW

BIOS is recently updated. Currently at the latest version and patch. 

 

PWR switch pins bridged do not start the PC either so it's no a problem with the switch. 

 

Furthermore, how would that explain the PC turning on on its own if the switch was broken. The switch is fine

Bump!

According to the manual, your motherboard uses a standard 20-5 pin PANEL layout for it's front panel connectors. Please send a picture of what you're doing.

 

Also, if you're bridging pins from the 24-pin power connector, there's a plastic shield there for a reason. Don't do that.

Try setting your memory to 3200MT/S 1.35v, and your fclk to 1600.. that might help. I have it in my head that its a memory issue. I think that a lot though when I see some peoples problems.. I got lucky with mine, but from what I understand Ryzen can be annoyingly picky at times.

If the switch was broken it could be making sporadic bridge signals…. Like if it was just almost shorted all the time…
