Lately my friend's computer has been playing up. Such events include losing internet connection (he had to "install" the internet again, which I don't understand) and now has lost sound. He has tried installing the drivers again but it hasn't worked. System restore hasn't helped either. Specs:
Motherboard: GA-P31-DS3L
Current 'culprit': Realtek HD Audio (on-board)
Realtek HD Audio is displayed with an exclamation mark in device manager.
