Black screen acer with cursor

Hello,
I have recently come into some problems with my laptop.
I dropped the laptop from no higher then one foot off the ground and it restarted when it came back on it loaded what seemed to be normal then went to a blacky blue screen with a cursor.
from here i cant do anything at all, my f8 doesnt work on start up. some times a blue vista screen will come up with no buttons or anything just the cursor still. I cant ctrl alt delete either, no processes work it seems.
if i can get some help i havent gotten any from the other links that seem to be having similar problems. if more info is needed just comment. I am posting this on my main cpu not my laptop
thanks in advance
Matt
