Hi,

You can try this work around.

Here's How:

1. Click on the Start button.
   If you're using Windows XP, also click on Run.
   
2. In the search box (Windows 7 and Windows Vista) or the Run textbox (Windows XP) type regedit and click OK or press the ENTER key.
   This will open the Registry Editor program.
   Important: Changes to the registry are made in these steps. Take care in making only the changes outlined below. While it's not a necessary step to complete this process, I recommend that you play it safe by backing up the registry keys you're modifying.
   
3. Locate the HKEY_LOCAL_MACHINE folder under Computer/My Computer and click the '> or (+) icon next to the folder name to expand the folder.
   
4. Continue to expand folders until you reach the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class registry key.
   
5. Click on the '> or (+) icon next to the Class key to expand it. You should see a long list of subkeys open up under Class that look something like this: {4D36E965-E325-11CE-BFC1-08002BE10318}.
   Note: Each 32-digit subkey is unique and corresponds to a particular type, or class, of hardware in Device Manager.
   
6. Determine the Correct Class GUID for the Hardware Device. Using this list, find the correct Class GUID corresponding to the type of hardware that you're seeing the Device Manager error code for.
   
   Hope this helps.

HI Friend, In this case I would recommend you to check if the CD/ DVD drive is getting detected in Windows Explorer or not ( MY computer) window. If it is not getting detected there then goto device manager and check if you have yellow bang on the CD/DVD drive option or not. If there is a yellow bang then you need to follow the below steps:
1) Close all open programs
2) Click on Start, Run, and type REGEDIT and press Enter
3) Click on the plus signs (+) next to the following folders

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

4) This folder is the DVD/CD-ROM Drive Class Description in the registry. Look for any of the following names in the right hand column.

* UpperFilters
* LowerFilters
* UpperFilters.bak
* LowerFilters.bak

5) If any of the above keys shown in step 4 are listed, right-click on them and choose Delete
6) After deleting the keys, close the Registry Editor
7) Reboot your computer
8) Open My Computer and check to see if your CD or DVD drives have returned. You may also want to open Device Manager and verify that the yellow exclamation anderror code on the CD or DVD drive is gone
### If CD/1) Close all open programs 2) Click on Start, Run, and type REGEDIT and press Enter

### IF CD/DVD is getting detected in windows explorer then try updating the firmware for CD/DVD drive

Do you have itunes installed?
If so Itunes put upper and lower filters in the registry key taking control of the dvd.
Goto Start type in cmd if it is vista, if it is XP click on run, then type in cmd, then regedit goto these keys in registry.

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

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{6D807884-7D21-11CF-801C-08002BE10318}

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{CE5939AE-EBDE-11D0-B181-0000F8753EC4}

Goto each key listed above and delete upper and lower filters then close out of registry editor goto device manager go down to dvd/cd rom drives right click on the dvd drive and delete it and if asked to delete drivers for this device check box to delete drivers then close out of device manager and restart the computer.
These upper and lower filters will say something like Gear Aspi.

click the + on the CD DVD drive you will find the you find the exclamation mark right uninstall that driver and Reboot your system and the issue was resolve .

Regarding the touchpad (curser pad), there maybe a problem with your touch pad driver not working or starting up. Check in "msconfig" (you can click on start and run, then type msconfig to bring it up) and click on the startup tab to check which of the startup items are not working.

Also regarding the card reader, i believe the drivers are not installed. Check in Device Manager (click on start /control panel /system icon /device manager) and see what is listed under "other devices"
