Error Code 19 on Buttons + OSDs ACPI driver gen2

Question

I have a new error window that has started popping up every time my computer reloads and not knowing how to fix it is driving me crazy!

Whenever I turn the computer on (HP Touchsmart 600 series) a small error message comes up with JAN2OSD in the top of the window and "Can't Open ACPI kernel Mode Driver in the text box of the window. I've checked in the Device Manager and found the little yellow triangle next to

"Buttons and OSDs ACPI driver gen2" when I click on that device, under the general tab I get the following error message:

"Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged (Code 19)

I tried Update Driver but it came back saying the driver is up to date and installed correctly. I have tried googling this error to find a fix myself but have not had any luck so far.  I am tempted to uninstall this device driver and hope that Windows re-installs it correctly but loathe to do this unless I know it won't adversely affect my system.

Incidentally, on the advice of a tech friend I ran a program called Combofix that I downloaded from www.bleepingcomputers.com to fix another issue that I'd been having - and running this program did indeed fix my issue, but this problem started occuring soon after so I'm not sure if it's related or not. Simultaneously I've also had my previously personalised background change to a Windows stock standard background and my computer will no longer allow me to use my photo collection as source for a screen saver which I've always had and want back!

Hope someone can help!

Thanks in advance, Kat
