Hi. I recently formatted my dell Desktop computer Intel(r) Pentium(r) 4 CPU 3.00GHz 2.99GHz and the computer lost all sound. I have tried in vain to reinstall SoundMax Integrated Digital Audio. It is nowhere in Device Manager. This is an on-board sound card. I suspect that I need to upgrade the motherboard drivers (but I really Do Not know what to do). I have tried reinstalling dell sound drivers from CD But still no help and I have reformatted the Disk C more than five times. I am running xp sp3 pro. Please help.
