xbox 360 freezes

After 30 minutes pf playing a ga,e my xbox 360 makes a beep then the system freezes. I have confirmed that it is a problem with the console. (No 3 red lights of doom btw) I still have my 2 year warranty on it from gamestop, but i cant find the damn receipt. Would anyone know if they keep it in their computer system of info?

i had the same problem when i had my 360(trade it in and got me a ps3 and i am happier )
i went to gamestop and got me a cooler, it helped alot..
