I have a three year old Asus A6000VM laptop which came with Windows XP and just reformatted the hard drive and installed Vista Business. No problems and all fine except that I get the message above and have no sound.
The Microsoft driver is recognised in Device Manager (with an exclamation mark) and, in the General tab, status is cannot start (Code 10).
I have tried disabling and un-installing and re-starting from both sleep and shut down mode but no success.
I have also down loaded the Realtek AC'97 driver for Vista. This is now shown in Programs and Features in Control Panel but will not load up even if I block the Microsoft driver from starting .
