PC randomly rebooting

[orriion]

Hello all,

 

I'm posting here because I'm facing issues with my pc that I have built only 4 month ago... It's randomly crashing whithout any BSOD or logs in windows logs.

I went on different forum for person that had same problems than me. So what I have tried so far:

 

Temp check for CPU & GPU -> OK

Memtest of the RAM -> OK

Default settings in BIOS -> Not working 

Change SSD with a fresh install of Windows on it -> Not working 

 

Corsair HX750 80Plat
RTX 2070 Super
Ryzen 5900x
ASUS TUF GAMING B550 PLUS
G.Skill F4-4000C19D-16GTZKW 2*8GB DDR4 4000mhz
Be quiet! Silent Loop 2 240mm

 

I changed my actual PSU with old one which is S12G Seasonic 550W and it was more stable but it crashed once so I don't if it because the S12G has only 550W or because another underlying thing. I've also tried the Multi/single rail.

 

Please help me

try re seating your cpu.

Seems like your PSU is faulty. 550w will be very close with this system, so that's probably why it crashed on the Seasonic. Might help if you undervolt the CPU and GPU or lower power limits, but you should RMA that Corsair PSU.

Thanks for your answers. But if the problem was the CPU seating. Why the problem is occuring after 4 month ? 

And it's even rebooting when it's on the ASUS logo when trying to boot. 

 

Anyway, I'll try to reseat the CPU. Also if I want to change PSU which one should I take ?

Thanks
