anyone?

Recently I noticed that my hard drive seemed to be running excessively and slowing my computer down. Using Process Explorer I noticed that I had Hardware Interrupts using up as much as 50% of my CPU.

I have scanned my computer with Spybot, Adaware and Symantec AV and everything was fine. I am running WIN XP with the latest updates.

Here is the log file from Hijack This, if it helps:
