I recently had boot up problems with my Emachines T 3410 with Windows XP Home Edition. We eliminated several apps. and finally realized it was a driver problem with the wireless. The result was that the computer works well now, but there is no sound, no sound icon and no sound equipment is installed...the installation wizard did nothing. Would installing a sound card solve the problem or do I need a driver? If a sound card is the answer, how do I disable the mother board sound.
