I have a HP Pavillion dv9000 Entertainment Notebook. AMD Turion(tm) 64 X2 Technology TL-60 2.00 GHz. Ram 3.00 GB and 64-Bit Operating System. I had Windows Vista and did a clean install of Windows 7. While using Vista, I burned important files onto DVDs. After installing Windows 7, my DVD/CD Rom drive is not working. I tried to update the drivers but I couldn't find them. I went into Device Manager to update them, but it's missing. I put in both a CD and DVD to see if it would pop-up and nothing. I went to Microsoft and tried their Fix-It and it couldn't find any device. URL here: http://support.microsoft.com/kb/982116. I then went and followed the advice at this site: http://answers.microsoft.com/en-us/...-missing/b768bfbe-652a-43b8-ade3-29969d26b000 and no such luck. The only thing that could possibly be a problem is something called a Coprocessor which is giving me an exclamation point in the device manager. I think it's related to a missing driver for the memory card. I'm prompted to go to the HP Company website to udpate it but I get an error message any time that I do so. Please help.
