When I insert a CD, DVD, software disc, etc into the tray, I hear 2 beeps, a fast, whirring sound which then stops, but there is nothing else happens. No little disc icon appears on screen. I'm unsure if the drive ever worked, but I assume it did when I installed the disc that came with my latest printer. Windows help & support helped me figure discs are not being read, and led me to find CD/DVD driver in Device Manager for repair or updating drive***THERE IS NO LISTING FOR CD/DVD DRIVE THERE OR UNDER SOUNDS SECTION IN CONTROL PANEL. I have a Compaq F700 notebook running Windows Vista. There are 2 DVD players listed in programs in addition to the Windows Media Player. No luck with any of them. One shows "No Disc" even after disc is inserted. Any help will be greatly appreciated. Thanks.
