I'm using the iGPU (HD 530) so can't do much there.
The whole PC is 3 months old, everything is freshly bought.
I did try default BIOS settings, it freezes under 12 hours, when I disable C states, EIST and overall play with the settings, I can get extra days (up to 9) without freezing (though it seems the latest BIOS update makes it so it freezes every day no matter the settings).
This is a non-k CPU so I'm not overclocking (not using the BCLK OC if that's what you mean). Although, most stuff in the BIOS is set on AUTO so it might be OCing it without my knowledge.
Temps ae around 35 when idle, go up to 60 when gaming, go up to 80 when stress testing. The board is around 40 at stress but worth noting the freeze happens no matter what I do, even if I idle, it's like a timed event. Event Viewer gives no info around the time of freeze.
In case you haven't seen this, it does seem to be tied to this:

P.S. The Pc was under heavy stress testing for a whole week (Prime, Memtest, Furmark...) when I sent it to the repairs, nothing happened, all worked well.
