Fujitsu life book AH502 problem

[Candace_6]

Hi I have the Fujitsu life book AH502 and last week the number 5 on the right hand side continually presses across the screen. Due to this I cannot do uni assignments without it filling the screen with 5's it also does it in bar for web browser. I tried cleaning the keyboard which stopped it for all of an hour but it's back to doing it. How can I sort this please?
