under "Other Devices" in device manager:
Multimedia audio controller
PCI Input device
My mobo came with onboard audio but I have an upgraded audio card. I have installed the driver for the audio card but not the onboard audio. Could that be one. Also, the driver I have installed for my GPU apparently is for two in SLI. I have another card I can install if you think could be the other. If not please let me know what they are, if I need them where to find them if I do and how to get rid of the yellow ! if I don't.
