Whats wrong with my xbox?

It means that it is overheating, if you are going to fix it yourself it is a good idea to get a video Xbox 360 Repair guide or send it in.

Go through it all again and make sure you have not missed anything.

One or both heat sinks is not making full
contact with the chips .

Open the unit back up and remove the
washers all of them their not needed.
just tighten the G.P.U. heat sink evenly.
not to tight.

The C.P.U. heat sink will also need to be
reseated if it got pulled , just push down
firmley on it and that should do it.

Hi,
The x-clamp or repair kits, are quite efficient And effective.
But the actual Torque/Tightness of the Bolts Are very Important.
Usually when a 360 Overheats, with the original X-Clamps fitted. The motherboard Warps. The method is to :- repair the cpu/gpu heatsinks, apply a small amount of thermal Compound, And gently pinch-Tight the bolts. Then Run the xbox without the Fan Connected for a few Minutes to heat-up the Motherboard. then clamp the bolts a little tighter. these can be awkward, but with trial and error are usually repairable.
Also to be noted, are the older style heatsinks ( without Copper heat-Pipe ) are not as efficient as the newer or revised version.
