After booting the computer up and logging in I open Clementine (media player) and at various time have started other applications (including LibreOffice Calc and simutrans. After 5-10 minutes the audio goes into a loop (repeating the same part of a track that is shorter than 1 second) and after around have a minute the system freezes and the video changes to a pattern of vertical light and dark blue stripes.

This is happening often. Sometimes it happens in the situation described above. Other times the freezing and the screen going blank happens without any sound playing. I have not had this occur more than about 15 minutes after starting the computer.
