    Newly installed 980, unable to boot (safe mode freezes at classpnp.sys


    Just got a GTX 980 (Asus reference) and when I've got it installed it freezes at "Starting Windows" and I have to hold the power button it to restart it.

    When trying to boot to safe mode, the computer hangs on classpnp.sys

    I know it's not the graphics card as it boots on my friend's computer and I know it's not a huge deal with the computer as when I reinstall my EVGA GTX 660ti the computer boots fine.

    Any ideas? I've made sure it's properly seated with the 2x6pin inserted correctly. I've also tried reinstalling the geforce experience drivers.

    Found the problem, BIOS was in update F11 so I read up and found that update F16 improved VGA compatibility so I downloaded and installed update F18 and that fixed all my problems.
