Did this happen while you were trying it out on the USB, or had the installation finished and you had removed the USB and restarted?

After I had finished the installation and restarted

Were the nvidia d rivers installed in the driver manager? Was there any difference with the open source drivers?

I don't know, I don't use an Nvidia card

Was secure boot disabled in your BIOS?

Yes

Was it a laptop or desktop? In case of laptop it might have been using battery saver mode. installing https://github.com/linrunner/TLP might have helped setting it up properly if you don’t want to handle it yourself.

It's a desktop PC

What graphics card do you have? I can check if there are any compatibility issues, though there shouldn’t be unless it is decades old, in which case you might want to try out one of the more old hardware compatibility focused Linux distros.

Intel Integrated Graphics 4000 (on a i7-3770 CPU)

(I'm still probably not going to try again for the time being, but I figured I'd answer your questions anyways)
