Random Powering Issues

[PetrolGuy]

 

Hi All,

I have some weird issues. It started to happen 2-3 weeks ago, about a year since this PC was built. Sometimes and completely randomly ( sometimes daily, sometimes os fine for days) my PC just won’t boot - light on MOBO are working but no response when pushing the button or shorting the boot pins. It also fixes itself, sometimes turning whole system power off and holding the power button helps, other times it’s just waiting for some time that works.

Mobo: ASUS TUF Gaming B650 Wifi Plus
CPU: Ryzen 7 7800X3D
GPU: AMD 7900XTX
RAM: DDR5 G.Skill Trident Z5 Neo 2x16GB 6000Mhz Cl30
Power supply: Seasonic Syncro 750W gold

 

Any hints would be highly appreciated

You can troubleshoot with spare parts, or ask a friend to borrow his pc to troubleshoot your parts with.

Start with the powersupply and its cables.

when testing my power supply with a paperclip i heard a clack which was not present when trying to power on the PC with the button or when shorting proper pins. 
 

I have no way to borrow some parta to test any other components.
 

From different source i heard the most probable cause is motherboard - do you maybe know how plausible is that?

try running the ram at default speeds, so no "expo" or whatever they call XMP now.

 

otherwise buy new PSU, corsair,  superflower or segotep.

The powersupply does have a fan, maybe that clack was it moving?

 

It could be the motherboard, but without troubleshooting with parts you can't be sure.

I’ve checked it again and indeed it was a fan. Whole system is on warranty so I’ll get an RMA on the motherboard then

Originally i had an XMP profile used, but after countless tries, restarts and clearing CMOS it went back to default. As for now i am not able to power on the computer at all. PSU seems working well.

 

btw I thought Seasonic was a good psu manufacturer? I am mostly tied to this PSU because of my chasis

 computer turn on but won't boot: Dead CPU, BIOS settings, Insufficient power supply, Upgrades went wrong, Beep codes, Peripheral issues, Damaged components, Software or hard drive issues

The issue is exactly opposite. It won’t turn on. But when eventually it does, it works fine

I'd recommend, when you can get it to boot, update the BIOS/UEFI.  AMD motherboards often have rapid updates, so it could be a conflict involving it for some reason.  Make sure you update them in the order the manufacturer instructs you to.
