Internal DP8000 'Not detected'

Goodmorning,
The internal dp8000 of a Roadhog4 is not detected anymore, (version 3.19) at showday 1 it was running normal, at day 2 at the same place (it didn't move) it stopped working.
(I've tried everything what I could find) the usb ports on the motherboard are working properly.
I Would like to hear if there are more solutions to try, or that it's needed to replace the internal dp8000.

Kind Regards, Thomas
