This behavior may occur because of a startup program that is installed with the CyberLink PowerDVD software or the CyberLink PowerCinema software. The PCMService.exe program starts when the computer starts and interaction at some level between this and the Wireless reciever prevents the computer from becoming idle. Therefore, the screen saver and the other idle-related features do not start.

Additionally, this issue may occur if the PCM and DVDLauncher services are running in the background. The PCM service is part of the Dell operating system that is used to start media programs faster. The DVDLauncher is a program that is used for DVD playback. This issue also occurs in Windows Vista premium and in Windows Vista Ultimate because of the media center functionality that is built in.
