It seems you have a device that's causing an "interrupt storm." It's tough to diagnose this without the sort of tools a developer would use.
If *I* were trying to diagnose this, I'd use XPERF... it's not easy to use, and iit only provides limited support for Windows XP. It ships as part of the Windows SDK. I'm sorry, I know that's not particularly helpful. But I'm not aware of a simpler tool that'll help diagnose this problem (which is pretty rare).
