Now reassembly begins. You will basically be doing the exact same thing you did to take it apart, but in reverse. Once it’s reassembled, be sure that ...
An Xbox 360 is relatively easy to repair once you know how to. The materials that you will need are a Phillips screwdriver (drill is optional), sharp nose pliers (not pictured), 5mm plastic washers, 5mm metal washers, 5mm screws, Arctic Silver 5 thermal compound, and a torx star shaped screwdriver to fit the screws.
The first step is to take off the outer shell to access the parts. You will start doing this by removing the face plate on the front of the Xbox. This is best done by pulling it outwards while grabbing the bottom of the plate.
Next you will need to remove the plastic covering on the top and bottom of the Xbox. They are a little more difficult than the face plate because they are attached by a series of tabs. You simply need to locate these tabs and apply pressure while pulling up on the covering.
You are now left with the outer shell. It is connected in four places on the front where you removed the face plate. Disconnect these and half of the shell should come lose. The shells will still be connected at the back and there are two ways to take it off. The safest way to do it is to pry each tab that they are connected to but this is very difficult and time consuming. The easier way to do it is to continue to pull the cover back until it snaps off. The only problem with this method is if you have an old Xbox some of the tabs may break off if they are brittle.
Once you take off the cover, you will see the screws holding the other half of the cover on. Take off all of the screws except the black ones in the middle.
Next disconnect the power switch on the front where you took the face plate off. Now disconnect and remove the fan and then the board.
