ASUS UX31A windows 8 update went bonkers

Hey everyone.

I just upgraded to windows 8, on my UX31a. And there are lots of problems.

The screen flashes black at random times, the FN keyboard shortcuts dont work, the trackpad went berserk.

I have tried getting the ASUS drivers for these things, but it didnt alleviate the issues. Have anyone had similar problems and fixed them? Especially the trackpad issue is killing me, the PC is barely usable.
