Advice on possible faulty CPU

[Soundwave61]

Hey guys I was hoping for some advice. I recently built a new pc and had it running for about a day before it died and failed to start up again.
Processor : AMD Ryzen 5 3600
Motherboard : MSI X570-A PRO (AMD AM4) DDR4 X570
Memory : Corsair Vengeance LPX 16 GB 3600mhz
PSU : Kolink Enclave 700W 80 Plus Gold Modular Power Supply
GPU : Asus Radeon RX 5700 ROG Strix OC 8GB GDDR6 PCI-Express Graphics Card

So yeah it ran for about a day I got Windows 10 installed, a few other things ran a couple of games to check it out seemed all fine. Then it just died, tried firing it back up and it did eventually run again. I thought I'd update the Bios through the MSI Dragon program and after doing the recommend reset it never fired back up. Nothing on screen but all the lights and fans where running. Checked CPU power supply (I'm missing the CPU2 supply but I've heard it's not important unless intended to overclocker and the pc was running for a day without one)

So after a few checks I noticed the EZ debug LED indicator showing a PCU fault.
I did what they recommended :
"CPU-LED lit on: please reinstall the CPU and check if there is bending CPU pins or other abnormal on the CPU and CPU socket."
Well when trying to remove the fan the processor came off with the fan! The thermal paste stuck it to it. We'll I was as careful as could be, cleaned the processor and fan with isopropyl and checked no noticeable damage to the processor.
Thought well maybe i didn't fit it correctly when first putting it in. Refitted it, new thermal paste all back together.

Still the CPU fault LED is on nothing on screen. So my question is do I now try returning the Processor where I got it? Could it possibly be the motherboard at fault? Do I contact AMD about repair /replacement for the processor?

I bought the processor and motherboard on 24/05/20
Processor from Amazon
Motherboard from Overclocker

Btw it's late for me and I have work so I'll have to pick up from people in the morning. Just wanted to get this down before bed. Any advice is most welcome, cheers.

Ah, I do hope your right and it isn't a hardware fault. I started down that path as it was the Cpu fault light that came on.

Anyway I'll do as you suggested, checking the manual I need a jumper cap for the CMOS. Ill have a go tonight, off to work for now. Will report back after giving this a go.

 

[Soundwave61]

So I've done all that was suggested, both the bios flashback and the CMOS with no change. Still no signal to the monitors and the Cpu fault light on.

I followed instructions in the youtube vid posted above. The led was flashing as it does in the vid and stops after the right amount of time. Try powering back up and no go.

I'll try it over again with gpu disconnected, and 1 stick of ram and all drives disconnected. And dis/reconnecting the power connectors.

OK so I've disconnected everything but one stick of ram, aux power and cpu1 power.
Plugged in mains and switched on rear switch. Nothing happens as I'd expect.
Press on button, cpu fan and motherboard fan run. EZ Debug Cpu fault light is on and no signal detected on monitor.
No change after CMOS.
No change after Flash BIOS.
(I performed the bios flash as per the instructions of the video above. The motherboard responds in a similar fashion to that of the video other than after the process is complete no change to outcome).
I've also tried using all three similar output on the power supply for the Cpu1 power.

I don't think I can honestly afford to buy another motherboard just to check this one functions.
Unless someone else here can think of something I possibly missed I think I may go and do as Jamin280672 suggested and return both the motherboard and the processor.
I'll happily receive back whichever is still working fine.

What I find unusual is how the pc functioned fine for a whole day to cut out with me doing nothing (I was on a call sitting in front of it without anything running on it at all)
To then start up again without any change after which I thought "Oh better update bios incase that was it" to then dies for good. (sure I used what sounds like a bad way to do it through the MSI software but it is there own software, surely it wouldnt brick the thing)

Do people think there will likely be a problem with me returning these items?
My best hope now is that amazon replace the cpu and overclocker test and find no fault with the board, the cpu warning light was working as intended, all is right with the world and I ride my pc off into the sunset.

Is this too much to hope for?

Well guys i thought id give an update on the situation.
The PC is up and running again hurrah!!

I managed to get a replacement CPU quite quick from amazon so tried it in the motherboard and as many of you expected the same fault was occurring. Sent back the motherboard to OCuk and they replaced it and we're back in action!

I want to say thanks to you guys too, i'm not the most PC savy person and feel a little nervous attempting repairs. I've only just sorted it so here's hoping it doesn't conk out on me again.

P.S. I've removed the Dragon center app as advised and I'll stick to flash drive updates from now.
