I pressed F8 to get to the boot menu. I actually wanted to boot in safe mode, but then I saw the 'Repair' option in the menu, and from there I got to another menu where I could choose between System Restore, some things I don't remember, and the mentioned test. As far as I understood, it tested the RAM, and said that the results would be shown when I logged on - that didn't happen, but it seems to have fixed the problem.
