Okay here's the scenario. Up till yesterday my computer was running W7 with no problems, using a Creative XtremeGamer PCI sound card. Last night I installed Snow Leopard on my secondary drive and quickly found out that my sound card didn't work with OS X. I did some thinking and remembered that my mobo (Maximus formula), came packaged with some crappy sound card, the Supreme FX II. I looked up the audio chip and found that it had been reported to work with OS X. My plan was to have both soundcards installed in my system, but only have one being used at a time - XtremeGamer when using Windows, SupremeFX when using SL. The problem is that when I put the SupremeFX in my system alongside the Creative and booted W7 to check if it worked, Windows went apes**t and stopped detecting any audio device whatsoever. The first time I booted with both cards, it didn't recognize the SupremeFX. I loaded up device manager and clicked scan for hardware changes and my system locked up. I restarted and after that it doesn't recognize either one of the cards. I've tried both together, both individually, and W7 doesn't find anything. Obviously this is unacceptable. I'm not even concerned right now with getting both to work, I just want at the very least, to have my XtremeGamer functional again. How can I get W7 to recognize it (please don't say reformat, I don't have a current backup and would lose a lot of data) and get things back to the way they were? Please help! Thank you in advance!
