Battlefield 2042 crashing PC

I cannot figure out what is causing my pc to crash after playing Battlefield 2042 for about 40 mins on average.

Here is my problem, starting since around 2 months ago, my pc started crashing randomly only when gaming, specifically Battlefield 2042 and Helldivers 2. I thought it was a windows update that was causing me to crash since it started happening once I updated windows. I rolled back and the problem went away for about a week before it started doing it again. I got a new install of windows (kept my settings/personal files) directly from microsoft since one of the errors I get was event ID 86 (the one where a SCEP certificate is not valid for AMD on A microsoft link or something). It worked, for about 3 days and then the problem persisted, some updates to the games also happened around this time as well as forced windows updates where I didn't have the option to get away from them. Well Helldivers 2 functioned normally from here on after, and so I thought I only crashed instense resource hogging games, but I only played Battlefield2042 on medium settings (tried high and low settings as well) and I still crash. I have other games which I think are more intense than those 2 but play just fine. My friends can play Battlefield 2042 with some lower spec pcs than me and play it just fine.

I have a log of just now when I crashed after 40 mins into the game to see if it's a hardware problem or not. I have done nultiple stress tests like on gpu, cpu, ram, used Samsung magician to check the health (ran tests as well) of my drives and they are healthy. I can play the game either 2 matches or 4 times and it randomly crashes (around 40-80mins), and usually after the first crash, I willl crash again within 30-40 mins.

So far on almost every crash windows fails to create a dump file so I can't even check what is causing it, but on the only dump files it creates a mnonth ago it was mainly software issue according to "whocrashed" application, which were resolved. My current main errors are Event ID 41 (63) Kernel-Power, 161 volmgr (where it fails to create dump file), 1796 TPM-WMI Secure Boot not enabled on machine, and 86 SCEP Certificate enrollment initialization (my pc workgroup and link) failed.

Only thing else left is to see if it is the power supply probably failing, but like I said I can play many other games just fine like asetto corsa on high settings, which is why I was hoping to see if someone can probably read the log and tell me it is a power issue or somehting else.

I built this pc myself, so here are the specs if anyone asks because even MS support was suggesting my pc is not good enough for gaming on the recent games.....-_-

Ryzen 5700X (Modified Cryorig C7 cooler with Noctua NHL9 fan)
Asus ROG B550-i
EVGA 3060Ti XC (using PCIE 4.0 riser cable)
Crucial Ballistix 32GB (2x16gb) @ 3600MHz
4TB storage (2 x 2TB Samsung 980 PRO)

600W Enhance 7660B Flex-ATX PSU

Yes this is a tiny PC build (sandwhich style) but I have plenty of air flow from 2 side panels and have 2 top fans getting rid of the hot air by pushing it out of the case on top; the rear has the psu fan outwards to push out the hot air there. I have had this pc for almost 3 years already.
