hai all master in here, i have a problem with my xbox 360 rgh. this evening, i see my xbox 360 is full of dust.so i tried to cleanin up my xbox 360, without taking apart off the casing. i was looking in the bottom of the casing there is HDD inteernal dock, i open it up and pull the HDD internal. after that i put it back on to the HDD internal dock, after that i was conectting all cables and i turn on my xbox 360. the problem is it won't booting to XBOX 360 white screen, i dont know why?. i alredy check all cables its good and i'm trying booting without HDD internal but still it won't booting. maybe there's a master that have a same problem with me and got a problem solved. for all the answer, I say thank you master. sorry for my bad english.
