if you have any questions message me. This happened before so i knew how to fix it. not very hard. i decided to make this video because when i had this problem i couldnt find a video to fix it.

here is what you need to do:

Take apart xbox360

strip down to motherboard

take off x-clamps

take out heatsinks

put thermal paste/heat compound on gpu and cpu

Put heatsinks back on using screws and washers or put xclamps back on if your cheap

plug in dvd drive and fan

put the fan on top of tall heatsink and dvd drive

plug in everything(you wont get shocked i tried it)

turn console on it should boot up normal with fan on

(if not, tighten screws holding heatsinks)

now leave console on for about 3 min.

turn console off

leave it sit for about 20 min. or when white heatsink gets cool

now it should work when u turn it on.

(if not, message me) (less info)
