Help - Aurora R4 wont boot

The computer was in sleep mode, now on hitting the power button fans come on, but no LED lights on side and no signal to monitor. Here is what i have tried so far: 

-unplug hold power button, plug back in

-remove and reseat RAM and GPU

-remove and reinstall cmos batter

-clear cmos

All of these got the same not-results

-removed RAM and GPU, and started up, got 2 beep- beep code

-replace RAM Only - get 6 beep- beep code

Replace all, no code 

replace all, same result as before. 

If i start it up without the GPU i do get a response from the keyboard but no blink code. The lights just actually come on. Any help is appreciated. Would love it to not be the motherboard but concerned that it is.
