HP Zbook 15 G6 dual boot problems

So i baught a refurbished Hp Zbook 15 G6. Formated all drives and installed Win 10 and 11 on 2 different drives for dual boot. I use win 10 for solidworks and it crashed for the first time, before crashing the display turnd off and on real quick. After that i looked at the Task manager and found only my CPU in use of my GPU while hafing a RTX 3000 installed. I got all my drivers from the HP website itself and checked with the nvidia App.
