Windows 7: DVD (not working) not found in Device manager, 1 USB port not working

DVD (not working) not found in Device manager, 1 USB port not working

I have a HP dv6910us Pavilion and the DVD is not listed in Device Manager. DVD Tray opens and light comes on but does not play DVD. 1st USB port on left side gets - USB Device Not Recognized.One under it works and one on the right side works.

OS Windows7 Ultimate. It is running kind of screwy so I wanted to reinstall Windows7 but with the DVD not operating Can't do it. Seems like maybe something in the register got erased or corrupted. If I can get the DVD and USB port to work I won't have to reinstall Windows 7. Anyone have any ideas or similar situation?

Sounds like a missing driver. Check to makes sure you have all your drivers and that they are all the most current or updated version.

How is this done when the DVD/CD Rom does not show on the Device Manager? How do I find if drivers are current?
