Recently, my XP (Professional, SP2) box started to feel very laggy. The Windows Task Manager's Performance tab tells me that my CPU usage is at 100% (even while idling), and it doesn't relent even a little bit.

If I view the Processes tab, it shows that all processes are using 00 CPU cycles. How, then, am I supposed to find out what is using up my CPU? Are there any third-party tools that I can use to investigate this situation? I have a 2.4 GHz processor, and it's feeling like a low-end Pentium II at the moment. Quite frustrating! My machine has been crashing and freezing ever since this started, and I can't figure out what's causing this to happen.

This seems to have started around the same time I began to run out of space on my primary partition. However, I cleaned it up and I have free space again. I wouldn't think that being low on hard drive space would cause CPU hogging, though.
