I noticed that it is USB related but i tried to iso late to which usb item cauzed it and it appears that all my usb items actually cause it. I use a usb mouse a steelseries kinzu, a seagate hard disk and an external dac.

Is there anyway to work around this?

Why is this marked as solved? Did you figure things out? If not, best thing to do is run a JCGriff Report to send us, as well as turning on Driver Verifier and keep it on through any future crashes (remember to send crashdumps to us). Do not select the following checks: IRP Logging, Force Pending I/O Requests, and Low Resource Sim. The rest of them you should turn on. If you experience boot loop after restarting from turning DV on, go into Safe Mode and turn it off from there, then send us crashdumps.

I I apologise as I clicked on it accidentally and did not know how to undo that action. I was quite unwilling to create a new thread but did so as i though my thread would be ignored due to my accidental clicking. I have since followed the guide on how to post in my new thread,

Sorry for the trouble
