Question CPU and MOBO not working after only one day of use

[Kevkeev13]

Hi,
Explaination : I've build my own Pc with the specs below :

Cpu: ryzen 7 5700x
Cpu cooler: ARCTIC FREEZER A35 A-RVB
Mobo: MSI B550M PRO-VDH WIFI
Ram: Corsair vengeance 32gb Dual chanel kit
Gpu: PULSE RADEON RX 6800 XT
Boot drive: SSD WD S240Gb
PSU: Aerocool Lux RGB M 750W
HDD: Toshiba P300 1TB

After using it for a day, without having any issue, the next day, the computer won't start.
I can see on the mobo a led for the CPU issue.
To be shorter, I've tried the CPU on a other mobo who is working and the CPU is still not working.
I've tried another CPU (who is working) onto the mobo, and the mobo is not working too.

Is it possible the mobo damaged my CPU ? Have you got any idea what could happend to damaged my mobo and CPU.
No OC have been made on the PC.


Thanks !

Welcome to the forums, newcomer!

I've tried another CPU (who is working) onto the mobo, and the mobo is not working too.
What is the model for the other processor that you'd tried/tested? BIOS version for your motherboard at this moment of time?

Yeah I thought about it just after posting this thread. So what I did is update my BIOS on my other MOBO, put the CPU and it worked, so my CPU is not dead ! That's a good point.

For the other mobo, with both CPU its not working, the mobo wont POST and a white debug led light stay on the CPU's led.

I've tried to update the bios, check my PSU, reset CMOS and nothing changed.

I've also removed everything (ssd, hdd, ram) and try to start but still won't POST.

I've no burn trace or this kind of stuff on the MOBO so i'm a bit confused now.
