My laptop (ASUS N56VM) promped a Windows X update saying that it couldn't install it. I clicked the notification and once it installed the computer screen went black. I could still see and move the mouse cursor. Aprox 30 mins after, I got impatiend and hard shut off the laptop. When I tried turning it back on the computer screen is completly black, No mouse, No fan noise, you could hear the HDD running but no LED light saying that it was reading it. It doesn't boot. I took the CMOS battery out for a minute. And retried. The computer booted perfectly. Me, thinking that the issue was resolved I restarted it. Booted fine. Then I tried shutting it down. It happened the same thing again, No boot, no screen, no fan. I have tried taking the CMOS battery out again, for more than an hour. I got the CMOS battery tested for voltage. I have tried booting with and without the HDD, with and without RAM, with and without CPU. During the trouble shooting sometimes the laptop turned off by itself not even a second after I turned it on. Or it turned on by itself when I plugged in the charger. Idk what else to try. Please help!! I have pictures of the GPU and the insides of needed be.
