Okay, after a restore point of approx 24 hours ago, wiping xonar drivers, reinstalling from disk, updating to most recent driver and then testing, I got another blue screen. I just came back from restart, rolled back the Xonar driver and I slept and woke up successfully. It's a shame because the Asus support site and forums are horrible so I guess I just stick with this driver from last year. It's odd though. In the previous box I had this card in I don't remember having any sort of issues ever and it was paired with the same gpu.
