Error not less or equal ntoskrnl.exe

Hello,

I have a big problem concerning this error, I get a blue screen with error NOT_LESS_OR_EQUAL and then the pc restarts its self. It's being a nightmare to me, i have all drivers updated and i even deleted Avast and kept running on windows defender because I thought maybe it was Avast, but it's not. And after I installed BlueScreen view I got this report:
