This is far too ambiguous for anyone to help you with. Stop.

get a water jet or hire me and cut your tab button off like i did with your dad last night :)

This happens on my moms laptop (win 7)

idk why.

what op is trying to say:

when I am using my internet browser or playing video games. The active window I am using will randomly turn inactive even though I never switched windows and nothing pops up as an active window.

there really isnt a better way to explain it
