Do you use a tower ? Maybe that the hybrid part (I mostly tried on différents laptop with primus) which never work for me. Or may be the games I play. I tried Warframe, star trek online and planetside2 and my computer freeze after some time. I tried to wait 30 minutes, nothing. I tried to get some dump, no errors… I dislike windows and I try to migrate regularly but I have to go back to windows.
