My system has been slowing down (almost 4 year old PC) so I've decided to buy a new desktop PC. It has a built-in sound card (Realtek) but for some reason, I couldn't get the mic to work. I tried the mic on the old PC and it works fine. 
The technician told me to upgrade to Windows 7 to fix this problem, but I still prefer Windows XP.
Please advice. Thanks.
