Disable
Nero Scout from scanning for media when the system is idle.
(sorry for not writing this up completely on my own. I fixed a PC via remote with these instructions and didn't have an opportunity to take down the information myself) I've copied the following information:
Start / All Programs / Nero 7 Essentials / Nero Scout
then Nero Scout Options Windows / Indexing / folder / Clear All / Apply / Uncheck Enable Nero Scout (not "Unable") / Apply / OK.
MSCONFIG and removing NMBgMonitor (which is a Nero Essentials component) from Startup
Thanks to the good folks at
