Laptop wireless help please!?

ok so lets start this off i have a lenovo IdeaPad Z570...ive had it for 6 months now everything was good until a certain girl touched it and started using it and now its messed up...

anyway my router is a TRENDnet TEW-432BRP.

THE PROBLEM: ok when ever i try to connect to my wireless it will connect to the internet for about 5 minutes(if i dont do anything) then it will disconnect and when you look at the wireless list of possible connections it does not even show my wireless anymore. for me to make my wireless appear again i have to go into wireless profiles and delete the profile and it will show up again. If it is connected and i try to do anything, open a chrome, start wow, anything that requires internet will instantly disconnect.

i like to think i am pretty good with computers but this is one problem ive tried to fix for week and im tired and run out of ideas...
