Fortnite Always crashes (But other games do not, whether OC or not)?

I have a problem with Fortnite and although my GPU (MSI RTX 2070 GAMING Z) is overclocked and in all games (8 pieces) and in the GPU stress test (FurMark) it is going great and the GPU is max. 67 degrees hot.

But in Fortnite it always crashes (no matter in which situation sometimes fast sometimes it takes a bit). Even if the card is not overclocked and runs only with standard overclocking from MSI (1920MhZ) in Fortnite gamesboost, there are sometimes image errors… (But not so often, about every 2-3 matches once)

I already reinstalled the game and tried everything else.

As I said in all other games (8 pieces) it works great with both settings, ie standard clock or overclocking.

I think it's because of Fortnite, because hardware and software side (GPU driver us.w) everything works fine and there are no errors and this comes with my old PC, I had exactly the same problem.

Would appreciate an answer very much.

Restarted already?

Oh, I read it over

Yes I have.
