Vista on my HP Compaq 6710b doesn’t recognize inserted CD/DVD

I am running a 64 bit Vista on my Compaq 6710b computer. It was running perfectly fine. Lately, one day it started refusing to read my cd/dvds that I insert in the drive ( my one is D: ).

As usual, by ‘googling’ I found the following helps:

• Article at techarena forums: DVD Drive E: Drive disappearing from Vista Home Premium 64
• Another article at techarena forums: Disappearing DVD drive–not an upper or lower filter issue
• Microsoft Support(kb-939052) on: When you insert a CD or a DVD, Windows Vista may not recognize the disc
• Microsoft Support(kb-929461) on: The CD drive or the DVD drive does not work as expected on a computer that you upgraded to Windows Vista

Deleting the UpperFilters and LowerFilters as mentioned in Microsoft Support kb-929461 didn’t help the drives, rather created more problems of totally eliminating the drives from the face of the explorer window 😦

Nevertheless,even with the other helps above, I haven’t got the solution to my problem yet! Help me, if anyone can. please!
