Screen saver not woking after install Microsoft mouse.

[tanthedog]

I have same problem after installed MS wireless mouse, I try many
different way, I finally found what happened. If you have any DVD
player software installed in your system that is the reason for screen
saver not activate, Because DVD program are run in PC back ground,
Click on START, Click on RUN and type MSCONFIG click on START tab,
Scroll down and uncheck PCMService, ehtray, If you're using Power DVD
uncheck PDVDServ or any DVD player software
click apply and you're done.
Good luck.
