Recently my HP pc with win 7 home premium 64 bit loses focus on the audio driver and looses connection to my APC brand UPS.
Each time I reboot I must install the audio driver with Device Manager.
Then I must disconnect the USB cable from the UPS and re-connect.
Now all work fine until I reboot or turn on PC after shutdown.
At which time I must perform the same routine.
I have done all the virus and trojan sweeps I can think off.
I do not install Microsoft updates as a matter of course.
I have also uninstalled recent programs and reswept the pc.
The audio card is integral to the M-board, I guess.
Any suggestions will be appreciated.
