my friend has an XBOX non-modded... i told him to get a mod chip, but then he said his xbox is broken. i asked him what is wrong with it and he said it shuts off randomly so he didnt want to waste money on a mod chip... would putting in an X3 fix this -- maybe the power switch board or a bug in his xbox that running a mod chip over would fix -- or is there any way to fix this so my friend can buy a chip?
