I noticed a burning plastic smell

Something inside is cooked. There is only one way to find out what that might be.

I tried shining light against the monitor screen and didn't see anything. Does that mean that the connector for the monitor to motherboard is damaged?

as you noticed burning plastic smell coming out of the exhaust of the base part of the laptop then the screen itself might be alright. open up the laptop base to locate the video cable from motherboard to screen on left hand side to see if it is damaged at all.

The screen turned white/black
It powered off
You smell burning plastic


And you continue to play games on it with an external monitor.

You really, really need to find the exact problem and fix it.

I opened up the laptop and everything looked alright, and everything smelt fine. I tried to stress my computer out and see if I was able to locate the burning smell but everything smells fine. https/gyazo.com/24ee5119b77871f66f4f8264ae9546fd this is a pic of the motherboard

that somewhat orange colored connector to the right of the fan in the picture appears to be your video cable. follow that cable to the left hand hinge area & inspect the cable there to see if damaged or not.

yes I do, it only appears to be exposed in the area where I taken that picture. The wire's wrapping is completely intact inside the hinge.

you need a new videocable. what happened is the opening & shutting of the laptop screen caused the cable to rub against that snr plate which is part of the hinge assembly to cause it to fray. when you get the new cable, reinforce that part of the cable with electrical tape & put some of that tape on the side of that snr plate that rubs against the cable. if you are going to still use that laptop then disconnect the cable from the motherboard & insert that cable to sit above the white ribbon cable at the bottom of your 1st picture.
