Pavilion dv7 can't recognize CD/DVD drive, support "assistant" no help

Subject says it all.  Ever since I got this machine, it's had problems where the CD/DVD drive becomes invisible and can't be accessed by any means.  A reboot has solved it in the past but now that doesn't seem to work any more.  I'd reinstall drivers, but guess what, I don't know what type of drive it is (funny how that works), and Support "Assistant" is apparently ihcapable of figure out the model of this Pavilion dv7 ("Product name: loading..." from now on until the heat death of the universe), so that doesn't help either.  Anyone got a better idea than just blindly installing drivers?

Hi,

 

The drivers for CD/DVD drives comes with Windows ( ie with the Operating System - there aren't drivers that you need to download ).  The driver is located in C:\Windows\system32\DRIVERS\cdrom.sys.

 

First, try the automated fixit from Microsoft on the link below.

 

Windows 7

 

Vista

 

Check if the drive is now working.

 

If the drive is not working, from the Start Menu, open the Control Panel and click on Device Manager.  Click to open the IDE ATA/ATAPI Controllers.  Right click on the first channel and select uninstall.  Do not delete drivers if asked.  When uninstalled repeat the process for each channel.  Also if an ATA controller is listed, right click and uninstall this, again not deleting drivers if asked. Then open DVD/CD-ROM Drives.  Right click the drive ( if it shows up! ) and select uninstall.  Do not delete drivers if asked.

Reboot the PC and let Windows reinstall the devices.  Check the drive again.

 

If it still isn't working, run the automated fixit from Microsoft on the link below again.

 

Windows 7

 

Vista

 

Next, from the Start Menu, open the Control Panel and click on Device Manager.  Next click to open DVD/CD-ROM Drives.  Right click the drive and select uninstall.  Do not delete drivers if asked.  When the device has uninstalled click on the 'Scan for Hardware Changes' icon ( usually just below Help on the toolbar ).  Let windows reinstall the drive and see if it now works.

 

Best wishes,

Doesn't work.  Tells me that the best drivers are installed and then that they are corrupted.  And since the CD drive doesn't work, I can't uninstall and reinstall.  This is supposed to be a good computer--the second BIG issue I've had with it and its only 7 months old.
