Right now, I currently have windows xp pro w/ sp3 on my computer. I've been having a lot of problems with sound lately. Sometime when I would start the computer up, there would be no sound. Usually, I would have to go into the settings and click the options that were already selected. For some reason, I would start getting sound after that (without changing any settings). I think my sound card is dying and I'm going to get a replacement. I already know that I need a pci card. I use an old lcd monitor with built in speakers that provide me with clear sound. What type of card should I get? Should I go with 16 bit or 24 bit? How many channels should I consider (since I only have those 2 built in speakers)?
