Xbox 360 slim starting error

Hey so I got my 4G slim shortly after they cam out and it was very quick and overall good. Over time I got a 250G HDD and I as a put content on Iit its like it bogged down. I recently cleared it and my xbox ran sort of normal although it takes an eternity
to boot up and im cool with that. But as of today it acts normal as it starts, but it then just displays a black screen instead of opening the dashboard. Even though the console is on, it just shows the blank screen Any help at all would save my life! Please
help!

Xbox One and Kinect 2's exact size, cable length revealed

Of course it is quite a bit bigger than the 360 slim, the original Xbox 360 was bigger than the slim, I'm sure it's bigger than the Xbox One slim will be too. That's the point of releasing the slim versions later on. But it is only 2.4cm longer than the original Xbox 360, which is what it should be compared to, not the revised, shrunk later released versions.

Original 360 dimensions

309mm x 258mm x 83mm

Not much in it really.

xbox 360 slim, in Syracuse with TWC. Same error code.

 

Press and hold your finger to the power button until the console turns off then unplug it from the outlet for 30 sec then plug it back in and power back on. Hopefully it will start booting up normally.
