Just few days i had assembled my pc with intel dual core processor (2.6 Ghz) and had installed Windows Xp on it. Now the problem is that i'm trying to install realtek sound card on my pc, but can not install it. Whenever i try to install realtek sound card its not allowing me to complete the installation process on my pc. Can any body tell me that why i'm not able to install realtek sound card on my pc? Does any body know about it? Kindly help me out to get rid of the above issue.
