Issues with Philps DVD-RAM SDVD 8821

Okay everyone, I’ve tried everything i can think of, but here is my problem.
I have a HP Pavillion dv6000 laptop, bought in december of 2006.
I’ve just done a complete PC recovery, trying to bring it back to as good as it was when i purchased the laptop.
This didn’t work.
My DVD drive is integrated, however for some reason it says that it has been disconected.
It also says that there are problems with the drivers even though i’ve just tried to update them.
Any help would be MUCHLY apreciated.
If you need more information, tell me and i’ll post it.
