Just transported my PC to a friends house for a lan party. My audio device was working fine an hour ago before I drove up here. I've connected my pc here now and I've got no sound whatsoever and the card is not registering in device manager. Tried reinstalling the driver and it says i need to connect my card. Reseated my card in the PCI slot and its nice and secure it hasnt come loose. Besides I was very gentle with the pc and I've only journeyed about a mile over smooth terrain so it can't have got knocked. The only thing is, my PC might have been in sleep mode because when I set it up here, it said windows did not shut down correctly. Any ideas? I'm going to try a system restore now if I have one available but any other suggestions would be welcome. I still have onboard sound at a push.
