Windows XP Task manager system idle is at 98% but graph shows one processor nearly pegged

Running Windows XP on a AMD dual core processor. Occasionally after booting, logging on, and letting things settle down, the Task Manager shows on the graph that one processor is over 90% busy. Yet when one looks at processes running, system idle is at running around 98%. On performance graphs, the CPU usage bar shows as red with tiny amount of green. Only one user is logged on.

"I'd try googling for the sysinternals suite and run process explorer to see if that can give more information on what is running on the processors.

Failing that you can also run process monitor and that will tell you what processes are issuing file and registry I/O and see if something there is constantly busy (use the autoscroll option from the menus to see real-time changes)."
