    GPU drivers most likely. If you can get to run in safe mode, you could use DDU to uninstall and cleanup after old drivers it works only from safe mode anyway. After you go to normal mode it should use elementary MS drivers which you can upgrade with proper ones.
    If MB has IGPU, you could but with it only and clean old and install new drivers.
