Ryzen 7 2700x brick

[DenianWriter]

Specs:

CPU: Ryzen 7 2700X with stock cooler

Mobo: MSI B450I Gaming Plus AC

RAM: 2 x 8 GB Ballistix Sport DDR4 3,000 MHz CL 16

GPU: XFX Rx 580 8gb

PSU: Corsair CX450M 80+ Bronze

Case: Masterbox Q300L

 

Bought a secondhand Ryzen 7 2700x, box was unopened and everything intact.

 

Could not get it to boot with a different mobo so I returned that mobo and purchased the current one. Still didn’t boot.

Both times the fans would all turn at max speed and the white motherboard LED would come on for the CPU, indicating a failure to detect the CPU.

 

Bought a new Ryzen 5 2600 and tried it on the board, got the same issue with a non detected CPU, was about to give up the. I tried switching out the ram. Switched from equivalent Corsair Vengeance of same spec to the current ram. It finally worked. So I the tried the 2700X with the new ram and it worked properly.

 

Installed windows 10 and the most current driver for the RX 580. Restarted the computer and it bricked.

 

The mobo’s CPU light comes on and the fans rev at max speed. Tried a different, third set of ram (Corsair Vengeance 3200MHz CL16) as well as all of the other pairs one stick at a time, and still nothing.

 

Took out the motherboard, cleaned the thermal paste off the cpu and cooler, reapplied new thermal paste (Thermal Grizzly, not liquid metal), and hooked everything back up without reinstalling the motherboard into the case. The problem is still here, cpu light on and fans wail at max speed.

 

Switched out the Rx 580 for my main rig’s 2060 and it still showed the same problems.

 

Tried it without a gpu and the same problems were still present.

 

The ram even works in my other pc so I really don’t understand what went wrong. It was working not too long ago when I installed windows 10 and that one driver for the Rx 580, but now it is back to the state it was in when I had defective ram.

 

I’ve built 4 PCs and this is the first time I’ve ever had problems.

And now it’s working again???!

 

Nothing changed and it just booted out of nowhere.

 

Im very confused and I don’t feel confident selling this PC to someone (which is what I planned on doing)

Im going to ask the obvious;  It might be a botched PSU.  CPU light means its either DOA or the BIOS is botched or CPU is bricked but that is rare.

I was also going to recommend testing the machine with a different power supply. Sounds like it's on it's way out.
