Hello all I have a HP Pavilion g6 laptop running Windows 7.Back in May upon starting my computer a red X appeared over my sound icon. I figured something was wrong but couldn't find what it was, so I did a system restore. Tada everything was fine. That would work for a few days then the red X was back. Eventually the restore day that I was able to set it to was no longer available and here it is a day from August and I still have no speakers. I looked in the Device Manager and there are yellow triangles over the High Definition Audio Controllers and the Composite BUS Enumerator. The Audio controller has a message in the device status that says "Window cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged or that might be malicious software from an unknown source". I haven't the slightest clue as to what happened. The only thing I can remember happening before the change was a Windows update.Please help. Thanx in advance

G'day Aisha, and Welcome to BC.


Go to device manager and Uninstall the items which have yellow triangles beside them. (right click, select uninstall, then confirm)


Then reboot.


If the gods are smiling today then windows should install new drivers where necessary, automatically.

If the above does not do the trick, try deleting them again then go to the HP driver site.  It will scan your system and the supply the diver or drivers needed.
