Boot Problem

[dman]

I just installed the X2.1 pro and when I boot it up it boots up twice and makes a wierd humming noise at first and then I get a Green/Red Blinking Light with nothing on the screen.I read in a tutorial that this means probably a bad chip. But the Xbox does work the the chip turned off....on when I turn the chip on and boot does it do this. Does anyone else know about this and what else it could mean? I'd like to rule out some possibilities.

Thanks,
