I used the program Bluescreenview, I'll paste the information it gives. Hopefulle you guys have any clue. My first thought: some defect hardware since I get different kind of blue screens within a short time. Hopefully the RAM in that case.
The computer rebooted automatically after each BSOD without any problems.
There haven't been any changes in hardware or software recently with the exception of Windows updates right before the first BSOD previous week.
