I am running the scan now.
I forgot to mention that when the sound is gone, no full screen applications will launch. Like games f.ex. One of two things happen:
They come up as a black screen and hang, or they come up as a small white ‘window’ where clicking anything comes up with a ‘This program does not respond’ promt.
At the worst point I pressed ctrl+alt+del to get task manager, because alt+tab doesn’t work in this state, and the entire computer locked up for about a minute. Then it popped up with a promt saying something about the system shortcut being unable to execute. I have never seen that particular error message before.
After that it returned to windows and I was able to close the program and reboot. (since everything stopped working again)…
That’s when I thought I was really fracked, but I haven’t had anything that bad afterwards.
The scan finished now, and said that windows resource protection reported no integrity… transgressions? (Windows ressursbeskyttelse fant ingen integritetsovertredelser).
I believe I should just reinstall the computer, and hope for the best. It is strange, because the problems just started 5 days ago. No notable changes had been made to the computer which has been working perfectly since I bought it two months ago.
