If I do a restart before the device stops, it reboots without a problem. I have to do a hard restart to get the system working properly. I've also noticed that when I restart from the no sound device status, the computer restarts but the screen is blank. If I reboot, the sound is restored but fails again at a random time whether or not I am doing anything. Driver Properties reports Error 43, and notes: "FW Dump detected."
