Although I am very sorry these things happen, please notice that we are "asking" for these kind of problems. And yes, of course I urge you to it.
The least you can do (at trying Q1 values) is not setting the thread priority so high. It may help. Once you found a good setting, yuo can set the priority back.

I knew it were the drivers, creative is known for sh*tty drivers. It's the need for a cold power up that scared me.
I used the same settings as GerardA (Q1 = 11, Q2,3=18, Q3,4=0, KS) before without any issue. Those settings are my favourite with the x-fi.
