Anyhow, at some points while using this laptop the pointer would randomly go off into the corner of the screen. Whenever I tried to move it from there it would resist from movement. I installed the drivers for this laptop but it still does it. Any help is appreciated.

(I'm afraid to contact Dell about this laptop cause I bought it at a Yard Sale. I tried to once but apparently I guess the phone number and name didn't match the the info on the Service Tag and they were asking me weird questions.)
