Is this a problem that just arose after using the computer for some time, or is it a new install? Dont use taskmanager to look into what processes are doing what use start run pviewer.exe you might have to get it from microsoft.com if its not installed on your system. Taskmanager when you get down to it is not a good place to look into these problems, start with pviewer
