Q: MacBook Pro Early 2011 will only boot in Single User Mode

So my Mac decided to die I think. Here is what I have tried. It is the early 2011 version so the HDD and memories can be swapped out (which I tried to no avail).

I used this page to boot from all the modes:

Startup key combinations for Mac - Apple Support

Safe Mode - The system hangs during boot up (Blank screen)

Startup Manager - The system hangs with any boot disk internal or external.

     Internal - the system hangs with blank screen.

     External - the system hangs with blue screen.

Apple Hardware test - All hardware passes the tests.

OS-X Recovery - Blank screen / does not load.

Reset NVRAM - The system reloads as it should and then hangs with a blank screen.

Single-User Mode - Boots fine. I can run fsck and the HDD is fine. It passes all the tests. Not sure if there is anything else I can run from this mode as it is the only way to get a working environment on the system.

Verbose Mode - I can see that the system hangs in loading different modules. Particularly those related to networking and wireless. I'm not sure if this is coincidence, timing, or in-fact there is something wrong with the network devices on it.

I was also able to pull the hard drive and successfully boot from that harddrive on my MacBook Air. So I know the HDD is working properly and the OS on there is working as well.

Any suggestions? Or is this system effectively dead?
