hi
does the aquaero work correct, when the aquastream is not connected? if it does, it's ok.
have you tried tor connect only the AS or AE (no mainboard, no hdd, nothing) to your PSU? are they working correct?
what kind of PSU do you use? how much power does it have and give to your system? maybe it is to weak?
it's also possible, that you have set the ID-jumper or working-mode-jumper on the AS-controller incorrect.
