I know this is a question asked a lot but, I just finished installing XP on my computer, and I have the whole no sound, Multimedia Audio Controller not working right and that, but I've attempted to download every possible driver for my computer that I can find, and none of them work. I have a Compaq Presario SR1750NX, would buying a sound card fix this problem? Only thing I know I can't do is re-install XP, I lost the disc :(
