Laptop behaving strangely

[Pushpak]

My Laptop suddenly started behaving weirdly 

Right click of mouse continuously happening randomly 

Things I have checked

1) no problem with external mouse

2) no software problem (since I have both ubuntu and windows same problem persists in both os)

 

What might be causing it

Is it's short circuit or Loose connection in trackpad

Or moisture since there lot of humidity in here 

Plz help

Then why did you post it in the operating systems section?

Probably, in which case the solution is to get the trackpad repaired or substituted.
