Something is keeping my mac from fully booting.

So the problems I am having arose a few days ago. It started with my mac randomly turning off. It happened many years ago aswell but I just unplugged the battery and put it back in and it worked again. This time around I could restart 2 times after it randomly turned off but after that it was done.

The only thing that gets the computer somewhat going is unplugging the power chord, holding in the power button for 10 seconds then plugging the power chord back in and releasing the power button (the light on the charger goes out when I do this). However I never get passed the apple logo and he loading bar underneath it. The fans are also running on full speed. When I check on the LED bar how much battery I have left the first light blinks indicating it is out of battery. Something that seems to be different from other cases like mine seems to be that my computer died while having the charger put in.

What I have tried:

-Reset SMC

-Reset PRAM

-Unplugged the battery

-Swapped the RAM to each others sockets.

-Different outlets for the power chord

-Let it rest with battery unplugged and power chord out over night.

-Used time machine to a previous build.

-Dusted the inside of the computer

-Tried to boot into my windows partition but that also stops at the loading screen.

I am out of ideas and was hoping you guys might have some ideas as to what is going on. Thank you in advance.

UPDATE: The computer turned on randomly again. It seems to be working fine. I'm posting a picture of coconut battery results.

Hi Mayer and thank you for getting back to me. I have a strange update.

This morning I decided to use your tips for troubleshooting. Plugged in the charger and to my surprise it lit up orange instead of green. I tried to start it immediately without success. I put it down to let it charge for a little bit. 5 mins after, it starts itself and everything seems normal. The charger does however make a buzzing sound from time to time. Not constant but every now and again it starts buzzing. Could it be the charger that caused all this even though the computer started with the battery unplugged?

You hit the power on button and the machine remembered and booted as soon as it had enough power. The buzzing sound is not normal. Let it charge up for a few hours. Every once in a while go feel the adapter. It should be warm but not hot. Once it is fully charged, download and run Coconut Battery to get a better idea of the true status of your battery and let me know your results.

I have the program up and running. Is there anything you would like to see? I'm afraid it doesn't make too much sense to be. It says the battery is poor which I already knew.
