Comment 52 for bug 717970

Hi, I bought a new pathetic Vostro 1540 and my keyboard seems messed up, everytime I'm typing, at any random moment, it seems like the cursor can suddenly appear anywhere on the screen and is really time consuming to repair phrases and words all the time. In the box I am typing right now it seems to have no problem whatsoever. Is there a fix for this? Do I need to know code? I believe I have windows 7 Home or Office edition... Any help appreciated.
