While playing screen goes black. Game comes back on and sometimes goes black again? Seens random when it happens and i dont think its happened in combat or moving fast. Seems to be a skyrim thing?

It has never happened to me. What I do get, are lagg, occasional freezes and visual glitches, but never that. Maybe you should try to clear the cache of your system if you have never done that before. I tend to do it once a week. If you don't know how to use it, just go to the system section, select the HDD and press "Y" button and select "Clear System Cache". This has improved my game's performance greatly.
