Sounds like a line in the Autoexec.bat or Config.sys, might be incorrect or Rem out. You may trying going in control panel and "Remove Hardware" and unisstall the sound card, then reinstall it, and maybe that will fix it.

If it is working fine with no conflicts, up-grade it, till you break it, then try to fix it, so you look busy.
My PCTel DAA AMR modem Really sucks!
If it is working fine with no conflicts, DON'T up-grade it, Leave it alone, and count your blessings!
If you are like me, sick of microsoft updates causing crashes, and making things quit working, inability to uninstall things, switch to Linux, where upgrades ARE backward compatable! Linux is FREE and Thousands of programs also are free for it!
