Windows 7: Sound stops working a few minutes after boot up

01 Jan 2012   #1

Windows 7 64 bit home premium
Sound stops working a few minutes after boot up

My sound stops working 4 or 5 minutes after booting up. I reboot and it works fine but stops working again.

I did some systems checks and had the following issues reported. I'm not sure if they are relevant to the sound issue.

- Universal Serial Bus Controller (USB) doesn’t have a driver
- SM Bus controller doesn’t have a driver

All my other drivers seem up to date.

Any ideas of what I should try???
