I have a HP Compaq DX2200 desktop, and i re-installed Windows XP SP2, it wasnt me who installed it. It was a friend of my friend. And ive tried installing many drivers for it but still no sound. Also when i was installing one driver "Realtek AC97 Audio Driver" an error came up and said "Microsoft Bus Driver should be loaded in your system before installing Realtek HD Audio Driver". And in the device manager, the SM Bus Controller seems to be in the other devices that are not installed or something, i dono about it, but heres a screenshot!!
And Please can somebody help me, if u guys know how to solve it, give me easy step-by-step instructions, because still im really new to computer drivers and those things!!
