My CD/DVD COMBO drive keeps DISAPPEARING off of my system. When I reboot the device and icon and everything is there but after about 5 minutes or less of inactivity the icon disappears and it will not work. If I use the device after rebooting it will continue to work until there is about 5 minutes of inactivity and then again the icon will disappear and it will not work. I have a gateway Pentium 4 2.60ghz desktop with 512MB ram and I am using WINDOWS XP SP3.

Please Help
Thank you
