wtf is this

im on my g73 was playing ffxiv and then wam the screen went black and a loud humming noise started what is that??

it happened a few days ago also but without the noise but it has long vertical stripes. and both times i lost complete controll of the computer i had to hold down the power button to turn it off.

is it the game or the computer.
could this be blue green gray screen of death i dont know what those actualy look like so idk



edit: ugh wtf it just happened again only this time the screen was green with a lot of black skinny vertical lines and again i had to restart my computer to get rid of it

what is this and whats causing it.

Try putting your computer to sleep (via key on keyboard) and waking it up again. It works for me.
