CD/ DVD Drive is not reading any discs! - HP Pavillion DV6747TX

Question

Hi there, I have a problem. My CD/ DVD Drive is not reading any discs! I have no idea what's happened..it was going fine and then all of the sudden it stopped working.
The computer I have is a HP Pavillion DV6700 or DV6747TX to be exact and the CD/DVD-Rom drive is a TSSTcgrp CDDVDW TS%L632N ATA Device. It seems to be present in the Device Manager and in the Computer Menu. When I put a CD or DVD into the disc drive lights are blinking and it sounds like it's trying to load or do something, but nothing is coming up. CD Drive E still says CD Drive E instead of reading the disc that's in there and when I click on Drive E it says Windows cannot read the disc in drive E.
I have tried searching the net for answers including the suggestions on this website and have tried a few other ideas I have come across but nothing seems to be working. Any help would be greatly appreciated
