I guess the CD/DVD drive is not detected in my computer
Then you can follow the following steps:
CAUSE-It may happen due to some corrupted registry keys in the computer. We can follow the following steps to delete the upper and the lower filters.
RESOLUTION/ WORKAROUND-
1. Locate the following key in the registry: HKEY_LOCAL_MACHINE\SYSTEM\ControlSet
2. In some cases, there may be multiple ControlSets. You may see something similar to the following HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002
Or
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002
3. Select either CurrentControl Set or the lowest numbered ControlSet, for example, in the second list above, ControlSet001, and do the following.
4. Locate the following key and highlight it in the left window of the Registry Editor. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
5. In the right window, you should see something similar to the list below. There may be some variation in the listed drivers for the upper and lower filters. For example, the upper filters may list a driver other that PWD_2K. You may also see only upper or only lower filters:
LowerFilters = CDRALW2K
UpperFilters = PWD_2K
6. Delete the upper and/or lower filters.
7. Exit the Registry Editor and restart the system.
NOTE: If the computer still does not recognize the drives, go back into the registry and repeat the above steps for editing the registry for each of the ControlSets listed on the system.
Hope it works for u
All The Best !!!!

Can't access CD


If you mean the drive won't open then
Turn off computer
Locate a small hole in DVD drive lid.
Carefully insert a straightened paper clip.
Gently push & the lid should pop out.
Then you can open the drive & remove the CD
Restart the computer and see if it opens normally and reads dvd's now.

If you mean Windows won't read it then the drivers may need re-installing. Check in hardware manager to see if Windows recognizes it or shows an error for it.

Can't use cd/dvd player - computer doesn't recognize it


try to boot the computer using cd. like you trying to install windows. if it read the cd to get into the windows setup, then cd drive is good.

1st make sure you set the option boot from cd first in the bios.
2nd place a windows setup into the drive.
3rd save and exit the bios.
4th if it ask you to press any key to enter setup then the cd drive is good.

maybe u have a windows problem, try to reinstall windows, that the easy way.

Compaq V2000 - Service Tag V2220US Only recognizes the CD/DVD drive as "CD" Does not see it as a DVD Drive. Listed as: _NEC DVD+-RW ND-6500A in Device Manager.


Try updating your drivers from www.hp.com

If the issue is that it won't play DVD movies only then you probably need to install or re-install the DVD player software that should have come with your computer. If you don't have it anymore, simply download from HP.
