Question System unstable, but ok when gaming ?

[natcha12]

Have a bit of a weird one guys,

It started when I was still on Windows 10 last year with an i7-6700 CPU, with random restarts at intervals of between 5-30 min after booting up.

I thought what the heck, I'll upgrade to Windows 11 to see if it helps because of the upcoming security deadline anyway but it didn't help at all.

Then I tried a clean install, nada. Upgraded to a Ryzen 5800X with same ram sticks, nothing.
Two more clean installs later, turned on dummy power loading in BIOS as a shot in the dark too, still nothing.
I tried out Ryzen Master at some point but I wasn't making much use of the gains so reset everything.
The current OS install has not touched RM and has had CMOS cleared beforehand too.

All throughout this though, it absolutely never happened while gaming. I'm talking pc game pass, steam, ubisoft. Anything remotely taxing on my system seems to stabilise it...

I'm currently setting up a memory scan. I'm at a loss what to do next. I've left Space Engineers open in the background while my PC has been re-downloading my game library for 3 days and it's totally normal.

Please help me check my emails and the news in peace!

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

Considering you performed an upgrade, we'll be seeing two sets of specs, one for before and one for after.

Where did you source the installer for the OS?

You're advised to reinstall the OS but in offline mode, manually installing all necessary drivers in an elevated command while in offline mode.
