Hi,
there is a small window that has enable and disable and the enable option is highlighted and I have clicked Ok but it didn't make any difference.
For the info about the driver where the yellow warning sign is called Audio bus on high definition bus.When I open the properties box and open the driver it has provider unknown and all the rest is unknown. Device status is the drivers for this device are not installed
Also I haven't been able to get the Add hardware wizard to complete downloading it says an error occurred and cannot complete, the same has happened with the system restore and also the fixit link in the post below.
