System becomes unresponsive during normal usage

[Roopa]

The system becomes unresponsive (including stuttering audio, slow mouse cursor, freezing)
after an hour or so of usage (sometimes more and sometimes less).
Usage at the time was a web browser idling (observed with both Chromium and Firefox)
and a music player (Clementine) in the background.
There were no CPU intensive applications running at the time.
