2700x microcode error

Evenings chaps :)

Had a nice fun start to my evening here, last night my pc froze mid game and I just hard it shut down and went to bed assumed it was just a generic problem that sometimes happens.

However today it won't give me an input signal on my monitor at all, checked all the connections and tried a different monitor and cables all the same.

At first I thought it was the GPU but that seems to be fine, all the lights come on no problem.

However my motherboard (Asus hero vi x370) is reading a post error of 02 which relates to an issue with the CPUs microcode. Unfortunately I don't have any spare components I can swap in and out. Do you guys think I should buy a cheap compatible CPU and swap it out or is it likely to be another issue?
 
From memory the C6H has the ability to reflash the bios without a CPU being installed, if indeed it is a BIOS issue and clearing it hasn’t resolved it, it may be worth giving this a go before spending anything on another CPU.
 
Bit random if it was fine one minute & then just died randomly but but it's probably worth removing the cooler, taking the CPU out, give it & the socket a quick blow and then putting it all back together.
 
Your signature appears to be very out of date.

That is more than likely very true!

It does indeed have this capability, I already gave it a shot using an older and newer bios but neither fixed the issue and still couldn't get an input signal on the monitor

Annoyingly I run a custom water setup in the smallest case I could fit it all in so doing so and replacing the parts would likely take upwards of 4 hours. Also it has been crashing semi randomly before this but I attributed more to the GPU than CPU
 
may sounds strange, but check your 3 pin cable to the psu from the wall is correctly seated in the PSU. ive seen this before on a way older system where the psu cable was looser fitting than it should be, bumping the case in the slightest caused the cable to dislodge and caused similar behaviour.
 
Simple test to eliminate the GPU as a variable if you don’t have a spare, the board will boot without a GPU installed, it takes longer and it will beep more, but it does boot.
 
How would that work? As there's no integrated graphics on the am4 chips so there's nothing for the monitor to plug into
 
Apart from the obvious of getting a different boot code, if it shows up on the network and responds to ping or depending on what you run, if you can SSH in etc. then you know it booted.
 
So I thought give a little update, it's very annoying I don't have anyone I can swap parts with near me to fault find.

I ended up purchasing a 3600 while they're on offer and it arrived today, swapped over all my components which included taking water-cooling setup apart, after flashing the bios to the latest one for the board using a USB stick I plugged it in and still the same error code.

After some furious trial and error to see if it could be anything else I've come to the conclusion it must be the GPU. Weirdly with the 2700 and gpu plugged in and removed I was getting the same error code whereas now with the 3600 I'm no longer getting the error code with the GPU removed, so unless it's a motherboard issue with the PCI slots :rolleyes:
 
Surely a motherboard issue?

If it's the motherboard that's at least the cheapest fix, however I would be surprised. Given I've swapped out which PCI slot the GPU is using and no change there, and it only hangs on the same boot error with the GPU installed since I changed the CPU. Since it crashed while gaming as well and has done previously that doesn't sound like a mobo issue but we'll sell
