PC randomly freezing, followed by black screen and restart, what should i do ?

First of all, i know, its hard to troubleshot it, i ve did so much research on google and there are so many people experiencing it and none of their adviced fix my  issue.
Rx 7800xt , r7 7700x, msi pro 650-s wifi mobo, gigabyte ud850gm 80+ gold  psu, kingstone fury beast ram, 4800 which can ran at 6000 with xmp or amd expo

Both of my screens will freeze at random points and then turn black and the pc restarts, usually there are no errors  event viewer besides the kerner 41 ones - unexpected shutdowns
But i got 2 minidump files that say the culprit is "amdkmdag" and "amdkmdag.sys" - this is the rare ocasion where it actually leaves an error, but usually it doesnt.
I sent the pc to warranty but the only testing they do is stress tests and playing fortnite and cs 2 sadly, i told them the pc must stay on for a few hours to actually freeze, not just 2-3 hours of playing fortnite. 
i tried different  recent drivers, tried minimal install and driver only, im running everything stock, no overclocking, i disable mpo and AMD ULPS, i tried each ram one by one, i updated bios.
They said they changed my cpu and psu cause they were faulty, they changed the cpu  cause i had a 7700 and now its an 7700x but im not sure about the psu.
Im trying to sue the company that sold my pc because they dont wanna even try to fix my issue, if it doesnt work, at least i wanna fix it myself somehow i know what i should be replacing in the pc to work

this is one of the errors -

Reinstall windows 11. If that doesn't get the crashes to subside then something like the hardware is faulty . The issue will eventually come back, and when it does, reinstall win11. However doing a clean install should be a short term immediate fix. There doesn't seem to be a long term fix

i did already like 4-5 windows 11 reinstalls, i tried messing in the bios too with stuff, still no luck. What do you think can be at fault, what piece of hardware
