just some further information, the PC will freeze (i can still move my mouse cursor but cant do anything), then it changes to a black screen with just my cursor for 20-30s, and then the blue screen happens for less than a second, and then the pc restarts.
As i am typing this my pc crashed again but no blue screen this time, all my fans and leds and stuff are on, my monitors are turned on, but nothing is being displayed.
The only thing i changed was turning off auto restart,
