DVD driver/registry problem

[KCav]

When I open Windows Explorer, click on Computer my DVD drive is not shown!

Device Manager sees it and places an ! mark on it. When I right clicked on Properties error Code 19 appeared - "Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged." I opened RegEdit and found CD/DVD ROM drives and made a screen shot, copy attached. Can someone help me find the corruption?

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

I ran Uninstall driver in Device Manager and then I ran Update driver. Device Manager said Driver is up-to-date but when I looked in Windows/System32/drivers it was not there. I enter PxHipa64.sys in Search for Programs and it said, "No items match your search." I downloaded the file and placed it in Windows/System32/drivers and tried to use the Manual Update procedure in Device Manager. I could not Browse to the driver directory, so I searched for the file with Search for Programs; again it said "No items match your search." :sarc:

I found the file name in Event Viewer, Error 7026. I wonder how can it be that Windows doesn't see file PxHipa64.sys except for Event Manager. Can someone explain this?
