Audio isn't working on my computer. I hear crackling, the audio will stop working and the computer randomly shuts down. Its not a heat issue. The card is an Audigy. Tried other speakers, and I think the random shutdowns are related as they seem to happen right after the crackling. The MB & CPU are brand new, just installed lastweek and the system ran fine for 5 days before the sound stopped working. Device manager says everythings fine. Tried moving it to a different PCI slot & the computer shutdown just as it was detecting it. Uninstalled & reinstalled drivers. Card works in other computer, the other computer is Windows 2000, mine is XP. Onboard sound works ok. Any thoughts?
