I have a Gateway DX-4200-09 64 bit with a Gateway keyboard model no KB-0817. For the last 6 months every time I reboot I get this error message "multimedia keyboard driver has stopped working". ...


The factory installed drivers and applications can be re-installed by using Gateway eRecovery

Click Start, and then All Programs
Click Gateway, and then Gateway eRecovery Management
You may be prompted to enter or create a password. This password will be required to use eRecovery in the future.
In the next window on the left toolbar, select Restore.
Choose Reinstall Drivers or Applications
Choose Contents
Choose the driver or application you wish to install
On the right, click the Install link and follow the prompts.
The computer should restart when installation is completed. If it doesn't restart, manually shutdown and restart the computer by pressing and holding the power button until it powers off. And then start it as you normally do.

Don't forget to rate this if it helped fix your problem.

Mass storage controller driver


Greetings,
IDE controller starts to install the driver automatically as soon as you restart. The best way to get it completely removed from your comp is that in case you are using Windows XP or higher version goto Safe mode by tapping the F8 key on the keyboard on restart. goto control panel to Add/ remove programmes and uninstall the software completely. I hope I helped you out.

Install the Driver manually, the automatic installation of the driver is not installing the drivers properly, that is why when you restart the system it is not able to identify the device. for this uninstall the driver restart your system then install the driver manually.

"a service installation section in this INF is invalid"


If the player is showing up in your Windows' Device Manager under "portable devices" with a yellow "!":

1.) Right-click the yellow "!" and choose "update driver".
2.) When given the option to connect to Windows Update, choose "no, not this time" and click next.
3.) Choose "Install from a specific location (advanced)" and click next.
4.) Choose "Don't search. I will choose the driver to install" and click next.
5.) Click the "Have Disk" button. Browse to C:\Windows\inf and choose the file marked "wpdmtp.inf"

I can't believe the generic players have such crappy support when so many people have this problem! I think the Windows file problem might be caused by "compressing old files" when you do a disk cleanup.
