Alien Isolation and Omega drivers = crash and restart?

[darckhart]

Installed the Omega drivers yesterday and suddenly Alien Isolation and general video playback (mpc and youtube) seems to cause lots of crashes and computer just straight up rebooting. Temps all seem fine. Heaven, IBT, Ryse, are all fine for hours. Just checking if anyone has any ideas before I try rolling back to 14.11.2
