For some reason, my computer's system resources lately have periodically been tied up by Hardware Interrupts, which cause everything to suffer a sort of delayed reaction. 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. My mouse moves in fits and starts, applications operate slowly, everything gets wonky. If I should try to play any media files, they play 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. 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.

I've done the usual things (run Spybot, HijackThis, emptied out my caches and recycle bin, done a disk check, etc.), but to no avail. Any ideas?

System in question: Intel mobo w/ 2ghz P4 CPU running XP Pro, 1mb RAM, 2-180GB HDDs.

Thanks in advance --

This issue is very complex and will need a bit of work to determine what's going on with your system. For a first step, I'd suggest that you run these 2 free online scans to ensure that your system is malware free. Once that's assured, we can move on to other software/hardware troubleshooting.
