Combo DVD/CD drive does not appear in Windows Explorer or the Device Manager

The combo DVD/CD on my laptop drive isn't in Device Manager or Windows Explorer.  The door is not ejected.  You must use a paperclip, poking into the hole to open it.  I also re - it sitting, but it changed nothing.  We had this laptop for 1.5 years and the disk worked great until yesterday when trying to install Starcraft II.  Installation failed and it has messed up also the DVD/CD drive.

We read some other difficulty advice and tried the upper and lower filters in the registry, but there was no entires of upper and lower filters in the key.

The specifications of the laptop are:

HP Pavilion dv7

Processor Dual-Core Mobile RM-72 2.10 GHz AMD Turion X 2

4 GB OF RAM

64-bit Windows Vista

Step 1: Please do all the same underneath if you did some before as is often total
a process that solves the problem.

Try this - Panel - Device Manager - CD/DVD - double click on the device - driver tab.
Click on update drivers (this will probably do nothing) - RIGHT click ON the drive - uninstall.
RESTART this will refresh the default driver stack. Even if the reader does not appear to continue
below.

Then, work your way through these - don't forget the drive might be bad, could be a coward
cable or slight corrosion on the contacts (usually for a laptop) and other issues.

Another possibility is that the cables are loose. Remove ALL power, then make sure that the cables in both
ends. Remove and replace, do not just tight. For laptops, you can often clean power and
contacts data with a pencil eraser.

Some DVD players do not use the Windows default drivers so check with the manufacturer of system and
manufacturer of device to see if there is a firmware or drivers for your drive if necessary.

===============================

Step 2: You have disc problems as the CD/DVD is actually 4 discs in 1 case (CD & DVD
Burn and CD and DVD read). So it is not unusual for 1 or 2 operational so that other parts
do it right.

Did you follow the Troubleshooting Guide for the reader who still does not work? There are
the entries in registry that the troubleshooter does not solve and those who "might" be the cause.

Check with your Maker system and a device for the two possible firmware updates and
the correct registry entries for your car.

Here are the keys that I of course are those in question - for the subkeys of the CD/DVD drive
as there will be other subkeys in these keys. Do not forget to ask specific keys involved as well as
the parameters.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\IDE

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Hardware Profiles\0001\System\CurrentControlSet\Enum\IDE

Use DevManView to locate the CD/DVD in the registry (be careful and do a prior Restore Point)
nothing change) - find the DevManView device and then make a right click on it free in RegEdit.

devices and their properties in flat table, instead of the tree viewer

  • "My external hard drive does not appear in Windows Explorer and cannot open 'Help and Support', an error message" Windows cannot open help and Support because a system service is not ongoing.

    Original title:

    Everything was fine until yesterday. Juice now, when I plugged the external HD into the USB port it does not appear in the 'my computer' window. It is recognized by the computer as it is present on the list of the "Disk Clean Up" and it also appears when I click on ' Safe Remove Hardware ' on the taskbar. But if she does not appear in the 'my computer' window I can't work with it or don't even know what it I have arquived in it.

    Trying to find a solution, I realized that same 'information system' to 'System tools' is also not available. Pops up a window saying that "Windows cannot open help and Support because a system service is not ongoing enforcement. " To resolve this problem, start the service named help and Support '. OK, I tried to open 'Help and Support' ' Start Menu ' and the same window appeared again to "not have a system service that runs". I don't know what her soul precisely and I have not the slightest idea of what I need to do to correct this 'disappearance' of Service 'system '. There is nothing without the appearance of HD in the window of thw work? Everything else works fine and the calculation is virus-free. What should I do?

  • My DVD/CD drive does not work in Windows 8 Professional, and it ISN'T a hardware problem.

    My DVD/CD drive does not work in Windows 8 Professional with or without data or audio in it. However, if I turn off the PC with a bootable CD/DVD in there, the PC recognize the media and initiate the CD when turned on. This confirms that the DVD/CD drive actually works, but for some stupid reason, Microsoft Windows 8 Professional will not recognize the same DVD/CD player it loaded since! Thanks again Microsoft for another product of shit. Now, how are you going to fix this? And how are we supposed to run things such as WordPad or paint, etc. I predict that Windows 8 will fall faster than Windows Me!

  • CD/DVD drive does not appear in Windows 8

    My CD/DVD drive no longer appears in Windows Explorer in point 8.1 of Windows on my desktop HP Pavilion Slimline 400-034. The disc rotates during startup. I tried the troubleshooting of Microsoft Window 8 with no luck. I would try the HP troubleshooting which requires access BIOS when booting, but by pressing F10 at startup me does not BIOS but Windows load normally. Any suggestions to at least help me get the BIOS?

    Solved! No. thanks to HP. Even if I had never opened the file on my PC and make sure that the cable DVD could not be disconnected, I decided to look for. Much to my surprise, he has been disconnected - but not by me - by a HP technician. I remembered that I had to return the PC to HP to replace the power supply warranty in June 2014. Not only have they not reconnect the cable SATA DVD, they put the cable from the hard drive in the MB connector where the DVD cable was supposed to be. After trial and error and insert the DVD cable in the 3 open SATA connectors with no luck, and finally move the cable from the hard drive to another connector and put the cable DVD where the cable from the hard drive was, the DVD has been recognized by Windows and working correctly. Thanks to HP for the many hours I lost to try to correct their mistake.

    Another possibility is that the cables are loose. Remove ALL power, then make sure that the cables in both
    ends. Remove and replace, do not just tight. For laptops, you can often clean power and

    Some DVD players do not use the Windows default drivers so check with the manufacturer of system and
    manufacturer of device to see if there is a firmware or drivers for your drive if necessary.

    ===============================

    Step 2: You have disc problems as the CD/DVD is actually 4 discs in 1 case (CD & DVD
    Burn and CD and DVD read). So it is not unusual for 1 or 2 operational so that other parts
    do it right.

    Did you follow the Troubleshooting Guide for the reader who still does not work? There are
    the entries in registry that the troubleshooter does not solve and those who "might" be the cause.

    Check with your Maker system and a device for the two possible firmware updates and
    the correct registry entries for your car.

    Here are the keys that I of course are those in question - for the subkeys of the CD/DVD drive

    the parameters.

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\IDE

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Hardware Profiles\0001\System\CurrentControlSet\Enum\IDE

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

    You can probably find more info here and maybe even the exact registry for your CD/DVD settings
    drive from someone with the same model.

    Use DevManView to locate the CD/DVD in the registry (be careful and do a prior Restore Point)
    nothing change) - find the DevManView device and then make a right click on it free in RegEdit.

    DevManView - free - an alternative to the standard Windows Device Manager, which displays all the
    devices and their properties in flat table, instead of the tree viewer
