ok, im having a little problem with a sound card i got about a year ago. its a Mad Dog predator blastwave 5.1, and i had it in my new computer for a few monthes now, and all of a sudden one day it stopped working. it shows up under device managerm even when i took it out of my computer, but it wont show up under control panel media devices. i took it out and put it in my other computer and it shows up as working fine, so i kno it has to be my computer. i have windows xp p4. ive tried to install it in another pci slot and it still wont work. ive uninstalled drivers and reinstalled, and still nothing. hopefully someone from here can help me out, i would really appreciate it.
