I haven't seen a repeat of that error and I've had three more of the xF4 with no dump. I think it had to be related to the nvidia update, which seems good now.
I'm currently running the seagate DOS disk scan to see if it may be HD related, then I'll see about any firmware updates I can make to the SSD.
Is there any way to check or test the MoBo drivers? Or all of them? Or should I just uninstall/update/reinstall with the best/newest I can find?
