So I was using Mac normally and suddenly the screen turned off and it shutdown. I simply turned on the computer again and the screen is pitched black but my usb connected keyboard is lit and it seems to be on the login screen because it sounds an error typing stuff. The fans are also on full blast. Because it responded to keyboard pressed, I decided to login to my account and sure enough it worked. I managed to get onto a terminal and typed "say hello" and it actually said the command! What could the issue be is it the video card? Would that make the fans blow at full force? I installed RAM a month ago and first tried that but after taking out the new ones it had no effect. I'm still within the 1 year warranty, would taking it to the Apple store be the best bet? I tried resetting the SMC many times but nothing changed. I also cannot tell if the nvram actually works because the screen is dark.
