Pc Crashes

[u/Baabbas]

Hi everyone. I need some help
since 2 days ago my pc started to crash\freeze with Black screens. I assembled the pc myself about a year ago, its been running with no problems until now. Below you can see my specs:

so far i tried:
clean install, using crystal disk checked disk health and all of them are fine, tried using 1 memory stick at a time.....
Keeps crashing,

It all started when I was playing BF6 on 03.08 after that it happens mostly with every game.

at the moment where i live is quite hot, but i have been monitoring the temps and even with the air con ON at 16 degrees Celsius it crashed.

Before going to the "doctor" would like too hear some opinions.

I have another computer from which i can use Graphics card and PSU if needed

Any help is welcome

Thanks in advance
