Win200Pro Re-booting

For the last couple of months my Win2000Pro based desktop has started re-booting on it's own, whenever it feels like it. The re-boot is normally preceeded by (an unknown source) large disk activity.

The system has been confirmed to have no viruses, trojans, spyware or any other form of malware.

Simple system maintenance like defragging etc.. has no effect.

I found a "hotfix" in the MS knowlwedge base, but it did nothing to help the problem.

Has anyone else experienced this?

Thanks

Andrew
