The game I was playing was Minecraft and not too long ago, it blackscreened again but this time I had my headphones on so I knew the computer was definitely responsive because the sounds were still playing. The current driver version 20.4.2 is already the recommended one so I guess I have to wait for a new version. However, I still have no idea why it happened only now as I've been using this PC for almost 2 weeks no problem. I don't know, I tried removing the watermark of Activate Windows today and I changed a few things in regedit but after the first blackscreen changed them back, however, still haven't restarted the computer. I will try to do that a bit later and see if the problem continues.
