Question Why my PC crashes/ turns off every game?

[elzmywaroo]

Hi
I don't know why and for me it's so strange, every game I want to play is crashing after loading screens or while it's loading. I tried a lots of solutions, read many of threads, nothing helped. The strange thing is when I turn on Fortnite. On epic graphic options it's crashing but when I turn it to low it's working :/
My spec:
AMD Ryzen 5 2600
GeForce 1660 6GB
16GB RAM
ASRock B450 Pro 4

What have you tried so far? Give us as much detail as possible.

That will save on people wasting your time (and theirs!) by telling you to do things you already did.

Right! So:
1) I've checked graphics card's driver and Windows Update
2) verified game files
3) disabled antivirus
4) reinstalled games (and even Windows 10)
5) contacted with supports of games
6) changed registry settings (in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers I've created QWORD (64-bit) Value as TdrLevel - set Value Data to 0).

That's what I remember.
