the crashdumps point to HIDCLASS.sys which is your USB driver according to my research, check that driver and see if it happens again

Hi Hacb,

Thanks for the reply. I did do a chipset driver update through AMD yesterday and haven't had the problem since. It does include the 3.0 usb drive. Much appreciated for the help
