I have an Aleinware m17x r2 with 2 Nvidia GTX 285m SLI, one burned out so i decided to upgrade. I went through the whole process folling your first post and now I'm stuck at the sound point. Leave it off in bios it works fine turn it on and it pretty much crashes. I wanted to know if you found a resolution for this and hopefully its not as painfull like it was to get the card to even work lol. ok I got the card to finally work and intalled all drivers. The problem im getting now is when I turn back on the IDT in bios and when windows is loading with the flag it pretty much crashes. So i have no sound atm. Anyone have aquick fix?
