all of a sudden my computer constantly hangs while idle. When I do something it can run the whole day normally but when it's idle it freezes. This all started to happen I believe after installing extra plugins for Compiz. Then I de-installed them, but still, turned off desktop effects to normal, still. First I thought it's my music player because I constantly run music on my computer, but then it happened also even without running any app. Please help, I'm running Linux Mint 9 x64 bit.
