Being driven crazy by Hardware Interrupts

For some reason, lately my computer's system resources have periodically been tied up by Hardware Interrupts, which cause everything to suffer a sort of delayed reaction. My mouse moves in fits and starts, applications operate slowly, everything gets wonky. When I consult Process Explorer, it says that Hardware Interrupts are using somewhere between 20 and 45% of my system resources, and System Idle Process (whatever that is) is talking up somewhere between 50 and 75% of them. This seems to be the case no matter whether I'm actually doing anything on the computer or not. It just zooms along, sucking up resources like a lush at a kegger. Sometimes this comes on if I'm I've opened a bunch of applications, and other times it seems to come on with just the basic system operations going on. If I should try to play any media files, it goes all jittery and juddery. I've discovered that one can't "end task" on either Hardware Interrupts or System Idle Process so the only way I've found to remedy it is to re-boot. Quel drag.

Any ideas?

Thanks in advance --

Robert
