my laptop was works fine but after a while it starts acting up. the cursor automatically scrolls down to the bottom of the page and refuses to scroll back up even when I try to do so (it sort of "snaps" back into place at the bottom of the page). the same problem exhibits even when i plug in an external mouse. i noticed when i press random keys i momentarily regain control. pls help me somebody!!!
i am running windows 8 version 2012. the laptop is a samsung laptop
