Well, he did say only explorer is running in task manager..so he has that part covered.
I was just thinking ti could be screen saver cuz that doesnt show in task manager.
He might also want to try downloading the "startup control panel" which is a great little app that works like msconfig but it seems to show more stuff....so maybe it would show stuff starting that task manager doesnt reveal.

Then again, he might just be able to look in msconfig to see what all is starting....maybe something there isnt showing in task manager.
