Getting black/blue screen

[VinzHD]

Guys i need your help with what the HELL is going on: So i got some bluescreens in the last few days since i installed my bluetooth drivers from the asus website. Yesterday i first got a black screen (my computer was still running but giving no display output signal) and neither unplugging the displayport cable didn't help nor restarting my monitor. I thought this had something to do with the ai suite 3 fan testing stuff i started at that time, But today i got another black screen with the same result. I only could restart my pc and nothing else. I also got the "renderdevice not found" alarm or something like that in overwatch on Saturday and if i have a bluescreen the error code is system_service_exception. When i had the blackscreen today my Bluetooth earphones would disconnect but my pc is still running.
