Random Roadhog freezes

Since 3.2 I have been experiencing several random crashes where the console is unresponsive. There is no real trigger to cause it, sometimes it will hang after idling for a few hours or while normal programming. Upon opening the processes window, the playback process has stopped and a log-off/on clears it up for a while.
The desk has generated two .dmp files, where should I upload them to?

The problem persisted when updating to 3.2.1 so no resolution with that.
It's a Road Hog with 2 playback wings and IOgear USB>VGA adapter, but the problem still happens with nothing but power to the desk.
