Question Unstable system - at my wits end

[HopesAnchor131]

Hello everyone

I'm really hoping someone can help me. I've been dealing with an unstable system now for over a year. Constant BSOD, random crashes and the system just becoming totally unresponsive.

It all started February last year. I put my PC to sleep and left for a few hours to do some shopping, I came home and woke my system up and the monitor would not display a signal, at the time I tried a new HDMI and that made no difference. Fast forward a few days later and with the original HDMI cable everything seemed fine which was odd.

However, ever since that my system has got worse and worse, crashes related to nvlddmkm.sys mostly also DPC_WATCHDOG_VIOLATION (133). I've tried reinstalling Windows, DDU display drivers multiple times and I have used memtest to test my ram and it came back fine. I have also updated the BIOS, which seemed to make everything go smooth for a week but just started even worse than before.

Also had a random reboot today with a new error from WHEA Logger, I'll paste it below.

A fatal hardware error has occurred.

Reported by component: Processor Core
Error Source: Machine Check Exception
Error Type: Cache Hierarchy Error
Processor APIC ID: 0

The details view of this entry contains further information.

My system specs are:
Ryzen 5 3600
Gigabyte x570i Pro Wifi
MSI RTX 2080 Super
Corsair SF750 Platinum PSU
Kingston HyperX Fury 2x8gb RAM

I'd really appreciate any support you can give me.

It might be worth trying sfc/DISM but that new install should have taken care of that.

Do you happen to have any other branded RAM available to try, even a single stick?

Are you monitoring temps?

What are you seeing in Event Viewer?

edit- not for nothing, but several of the YT hardware channels have come across a high rate of failures with the 3600. I am not saying that is for sure what you have going on, but...

Have also done the sfc/DISM multiple times, it has only ever changed a bluetooth driver and found no other issues.

I have no other RAM to hand unfortunately.

I am monitoring temps, CPU goes to 70c while gaming, GPU to 80c. Maybe worth mentioning another forum asked me to run furmark yesterday which I did, it only ran for 2 mins and the GPU reached 77c before the whole system totally locked up. I know when a crash is coming as the GPU fans slow right down and the screen flickers before ramping up again, crashing totally and slowing down again.

Event viewer just brings up nvlddmkm errors and kernal power errors etc.

This is my second Ryzen 5 3600 as my first died in 2021 along with my mobo, luckily they were still under warranty then. Back in 2020 along with being a PC newbie and a bit of stupidity I would mine with the CPU (which is probably what killed it) and this GPU too which could now be coming back to bite me.

Try something, if possible.

Take a regular house fan and set it up where it can blow directly into the case with the side panel or glass off and try some of these tests. Let us know how that goes.

Alongside that, if you are on a long extension cord, or a plug strip with lots of things plugged in, try to limit or turn off everything on that circuit that you can.
