I have an ESI Juli@ audio card with its driver installed. I've moved the card to another PC without uninstalling the driver, because I planned to put it back in the same computer after a few minutes. I had a problem with the other computer's audio, so I wanted to check it with another audio card.
Anyway, I put the Juli@ card back in the same computer and the computer didn't turn on properly, so I removed it and put it back and now the computer turns on OK. So I tried playing a game which worked fine before I removed the card for the first time, but there was no sound. I closed the game and launched the audio card's mixer software (part of the driver), to see if it's configured properly, but the computer crashed. Now the mixer doesn't launch at all, and my audio card doesn't appear in Windows' Device Manager. In fact, it's not even shown as an unrecognized device, which means that I can't re-install its driver.
What can I do to get my audio card to work back?
