Win XP Explorer.exe high cpu usage?

My wife's computer is having a problem with explorer.exe consuming about 98% of her CPU usage, making running anything virtually impossible.

Anyone have any suggestions? We are in process of fully patching it from MS, and have run every virus and spyware scan known to us, having cleaned off everything that could have possibly contributed to the problem.

Try this, Ep.

You are looking at processes; not tasks - correct? Now look at what that process is doing to consume so much time. Virtual memory? IO access? Page faults? Base priority? User name for that process? What is happening on the network connection? How many users are really on the machine? Do this happen for other Users on same machine?

What do the system event logs say?
