Windows 7: Win7 audio ceased to work, cannot install driver.

Win7 audio ceased to work, cannot install driver.

Windows audio stopped working. Unable to re-install any working driver because of the "unsigned" driver issue. MoBo is Formosa and there are no official drivers for win7. Win 8 drivers worked fine until this morning now audio dead and cannot install any working drivers.

It has all worked fine until yesterday I installed Screen reader to test. (not sure if that was related) It was working until I shut down last night now on restart I have no audio and tells me problem installing unsigned driver even though it also says that the latest driver is installed. The normal checks all say I have the correct drivers and that they are up to date however refuse to work. I have the chipsets for the mobo but re-installing gives me the same error regarding the audio driver.

I enabled the option in admin to allow override of unsigned driver error but that seems to have zero effect. (gpedit.msc) - "Allow admins to override Device Installation Restriction policies" Enabled.

Is there a registry hack I can try to disable checking for signed drivers?

Have screenshots of various messages but cannot figure out how to add those to this post. The image icon just asks for a URL but they are on my desktop not on a web site.

MoBo: IPMMB-FM, i7-3700, Win 7 Premium. TON hdd space, 32GB Ram.
