I'm sorry to send two E-mails in a row, but I just discovered some information 
and maybe it could help with figuring out what's going wrong. When I boot 
Windows in safe mode and go to device manager I see under "other devices" two 
PCI devices with yellow exclamation marks on them. One is called Multimedia 
Audio Controller, the other is called PCI device. Multimedia Audio Controller 
reports PCI bus 0, device 5, function 0. PCI device reports PCI bus 0, device 
3, function 0. Under "sound, video and game controllers" I see AMD high 
definition audio device, and under display adapters I see AMD Radeon 7900 
Series. AMD high definition audio device reports Location 0 (Internal High 
Definition Audio Bus). AMD Radeon 7900 Series reports PCI bus 0, device 7, 
function 0. When I go to details and look at the hardware Ids, I see that they 
don't match up between the unknown PCI devices and the AMD devices. When I go 
to the Devices and Printers area of my control panel I see that Windows reports 
my AMD sound and video devices are working properly, but my unknown PCI device 
and Multimedia Controller don't have drivers installed.
