Let’s do one test to see if we can isolate the issue. Restart your system but press the T key that should allow your system to enter in to Target Disk Mode if that works your screen should show either a FireWire or Thunderbolt port icon floating on the screen. If that works we know your dedicated GPU has failed. This is a common issue in this series.
Let us know what happens!

Thank You for your response and apologies for taking so long to reply.
Yes there was a thunderbolt floating on the screen when I held down the T key on start up.
So that means that my dedicated GPU has failed.
How can I fix it/ replace the GPU?

Sorry finding a good logic board these days for this series is very difficult! The GPU chip is not available any more from AMD (either Radeon HD 6490M or 6750M) as its production as long since ended.
Your best bet is looking for a 2012 system or logic board which offered a much better GPU - NVIDIA GeForce GT 650M.

@danj I would probably retire the system as a unit, transfer my hard drive and walk away from it. At that point I’d sell the 2011 for parts (no HD since I’m keeping it for the 2012), even though it works. Yes you lose money, but you can’t sell them for much and the buyer has a case against you if you GPU burns out within 30 days. They are known to fail and need to be sold accordingly.
I would probably replace as a unit and buy a newer 2012 to avoid having to try multiple boards to dind a good one, and to avoid a situation with mismatched serial numbers since that’s a potential logostical mess since you need to remember the machine’s board and bottom cover do not match.
What I would personally do is temporarily install a junk drive into my "new" 2012 and get the firmware current where I had MacOS prior as a step against EFI incompatibilities, but that would probably be it. After that, I’d swap the drives over and replace the HD cable if it wasn’t patched just to be safe if I noticed anything funky with the behavior of the system.

@nick - I'm not worried about mis-matched S/N's Even Apple does it when they replace logic boards! Both the early and late 2011 models have GPU issues.
I only swap-out the logic boards in the 2011 models with 2012 boards as its so bad. Sadly finding even the 2012 boards is getting hard.
@danj It's more of a management issue for me - I'm not going to shame you for it BUT if yours is a S/N mismatch and someone has a nearly identical match you lost me unless the mismatch is significantly better spec wise (or a special part like the HR AG panel) to make things even. If they're nearly identical, it's harder to overlook.
True I can notate it as a SN mismatch discretely on the bottom (I use a TZe labeler, so the labels hold up over time) and notate the true serial number so it isn't the end of the world but I just prefer a cover and board match. I can also save it for reprints as needed.
Knowing Apple is just as bad eases me a little on it to more like highly discouraged.
@nick - I have such a system a 2011 model which now has a 2012 logic board. I'm knocking this out on it now!
I think you're confusing your self! The board's S/N is the only important S/N.
Apple even has a procedure you need to follow when you replace a logic board. Marking the inside bottom cover or the case back with a marker the new logic boards S/N
Early on Apple wanted the tech to program the systems cover/case S/N to a virgin board but they ended that as once you set it you can't undo it! So Apple got a ton of returns as well as finding systems with wacky S/N's! I even encountered two! It was setup with a running number and a second with all zeros and a single number!
@danj Those early days where it had to match are why I'm so picky about it.
@nick -You lost me here? Do keep in mind you can't always jump from one series to another. This is one of the few that Apple didn't change the design that radically.
