If it works fine in safe mode with networking, perform clean boot to find the root cause.
Step 2: If it works fine in safe mode with networking, perform clean boot to find the root cause.
To help troubleshoot error messages and other issues, you can start Windows Vista or Windows 7 by using a minimal set of drivers and startup programs. This kind of startup is known as a "clean boot." A clean boot helps eliminate software conflicts.

NOTE: After you check the functionality in clean boot configure Windows to use Normal startup using the step 7 suggested in the link mentioned above.
Note: Do Not disable wireless services, if any.

Function keys are special keys used for assigning program shortcuts and specialty tasks to the keyboard.
They are located at the top of most keyboards and labeled "F1" through "F12."
Some keyboards may only feature 10 function keys, while others may have as many as 18. These keys often go unutilized by the average computer user, but they may have very important tasks for some users, which can lead to problems when the keys do not respond.
Fixing nonresponsive or malfunctioning function keys is quite simple, and should only take a few minutes.

Connect your keyboard to your computer, and power it up.
Open a program that uses the function keys such as Microsoft Word or Microsoft Excel. Check your keyboard for an "F-Lock" or "Function Lock" key.
This key is used to toggle function-key support; when it is toggled on, the function keys will not work.
Press the "F-Lock" key and then try using a function key in the selected program. "F1" is a good key to test, because it is set to open a "Help" document in all Microsoft software.
If the key does not work, press the "F-Lock" key a second time, and test the keys again.
If the keys still do not work and you are running the Windows 7 operating system, you may need to install a "hotfix" from Microsoft to fix the key functionality.

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

After the above :

References to Vista also apply to Windows 7.
Stage 1 : Please do all the below even if you have done some before as it is often the total
process which solves the issue.

Try this - Control Panel - Device Manager - CD/DVD - double click the device - Driver's Tab -
click Update Drivers (this will likely do nothing) - then RIGHT CLICK the drive - UNINSTALL -
REBOOT this will refresh the default driver stack. Even if drive is not shown continue
below.

Then work your way through these - remember the drive could be bad, could have a loose
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 check cables in both
ends. Remove and replace, do not just snug. For laptops you can often clean the power and
data contacts with a pencil eraser.

Some DVD drives do not use the Windows default drivers so check with the System maker and
device maker to see if there is firmware or drivers for you drive if needed.

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

Stage 2 : You could have drive issues as the CD/DVD is actually 4 drives in 1 case ( CD & DVD
burn and CD and DVD read). So it is not unusual for 1 or 2 parts to not function while the others
do so properly.

Did you complete the troubleshooter for the drive that still does not work? There are some
registry entries that the troubleshooter does not fix and those "might" be the cause.

Check with your System Maker and Device maker for both possible firmware updates and the
correct Registry entries for your drive.

These are the keys I think are the ones in question - for the CD/DVD drive sub-keys of course
as there will other sub-keys in these keys. Be sure to ask for specific keys involved as well as
the settings.

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

Use DevManView to locate CD/DVD in registry (be careful and make a Restore Point before
changing anything) - find the device in DevManView and then Right Click on it Open in RegEdit.
