I am no expert but looking at vmstat, I noticed that there are 1041 
interrupts received and 390 context switches.  On my system 
(workstation) I have 7 interrupts and 17 context switches.  On my 
workstation I have seti-boinc running and has been up for 25 days.

Also i/o waiting is at 73%.  Something is making allot of calls to the 
processor and thus loading it down.

What is causing all the interrupts?  Some USB device?  What devices 
are connected to the computer?  What services are running?  Try 
shutting services off until you find what is causing the problem.
