Random BSOD while playing Diablo3 - USBPORT.Sys 0x000000fc

Hi all,

Just started getting this BSOD today while playing Diablo 3. Seems to do with the USB port...but nothing unusual in device manager.

Attached is the SF diagnostic file.

Thanks in advance.

Your Atheros Valkyrie USB BootRom driver looks suspicious, can you update it here.

ATHEROS drivers for Microsoft Windows (Atheros?????)

Your display driver is also causing issues, please roll back the driver as these latest versions have been causing a few issues.
Here's some useful instructions.

Thank you for the quick reply.

The Atheros Driver is for the bluetooth module on the motherboard and it seems it is already the latest version from Asus website.

I will try and roll back to 334.89 nVidia Drivers also..
