HP PAVILLION DV5 mouse problem?

I have an HP Pavilion dv5-2035dx Entertainment Notebook and Ive been having problems with the mouse. I dont know if its a problem with my laptop or if its a flaw with the model. So, sometimes I can go thru the day and everything works fine. Other days .. a few times a day.. The cursor will jump very quick across the screen, back and forth as if I'm swiping my finger across it back and forth but i'm not touching it.. it does it on it's own. When it happens i have to hold the power button down for it to restart and then it comes back on and works perfectly. Anyone else have this problem and a solution?!
