macbook wouldn't go past apple logo now screen is black

[gbazmatt]

(macBook Pro 2012)

I have a double problem ,

the original problem i had was that when I was forced to shut down the computer by holding down the power button , when i rebooted it would not go past the apple logo, it would just fill up the line and never go past it.

tried

Shift+Control+Option+Power

and

command-option-p-r


then finally

Command-R just got me to the internet connection and then once again got stuck on the apple logo spinning

thinking it was my hardrive, i removed it and tested in another computer.... it's not the hard drive.

So i put the hardrive back in the original macbook , boot it up and now the screen is black now complicating the issue even further as i can't figure out how to connect an external monitor with it in this condition.

My next guess is RAM , can anyone with more experience tell me if this is what it sounds like?

Sorry for the long winded post, but I thank you in advance for reading it and possibly helping.

If it is under warranty take it back.

Any chance of liquid spills etc?

It's four years old and no there are no spills or liquid of any kind.

I'm actually more concerned with the first part as if i can get it to work on an external monitor, maybe I'll try replacing the RAM or trying different set then seeing if it actually boots in(then I can use my TV)

That pretty much covers it shshxiaojing. I am wondering why you had to force it to shut down with the power button in the first instance? What problems were you experiencing?
