OK, I need some help.  My CPU load is 100% when my computer is idle.  This has been happening for the past few days.  Nothing new has been installed on my computer, and I have defraged the hard drive and run antivirus.  Here is what is running:  Explorer, Wcescomm, wkcalrem, vptray, dadapp, syntpenh, atiptaxx, syntplpr, and systray.  I have no idea what any of these do.  Which ones should I shut off and how (I have ME)?
