Xbox evo x problem

i have an xbox with an evo x chip. i have never before had a problem it, until a few days ago. When i turn it on now, i only get the ms dashboard. i cannot access the games, the main screen or anything else. The only options i have are ms dashboard (which return me to the same screen), reboot, power off, settings and backup. Is there anyone out there that knows whether my xbox can be fixed and how. Any help would be greatly appreciated. Many thanks

Your chip has probably disconnected from the main board. You need to reconnect/resolder the chip.
