BSOD DPC_WATCHDOG_VIOLATION playing Guild Wars 2

Hey guys,

sometimes while playing Guild Wars 2 i experience a sudden freeze. It is impossible to open the task manager or anything else. Shortly after that, the BSOD appears.
I add the diagnostic information and hope you can help me! If you need any other information, I will provide you that ASAP.

Thanks in advance Attachment 98142

The bugcheck analysis points to a driver problem with the touchpad.

If possible see if you can find an updated driver from Medion.

I updated the touchpad driver from the medion website, but the bsod still persits. I made a new diagnostics .zip, if you would look at it again?
Would it help to uninstall the touchpad driver completely?
