Hello, I was playing some CS:GO when my suddenly my laptop screen went black and secondary display froze with displaying only brown lines on it. I shut down the laptop and have been unable to boot it up since. When I power up, all I'm getting is a black screen. The fans start rolling and power and blue tooth leds as well as keyboard backlight are on. USB devices aren't getting any power. I tried reseting CMOS by removing the battery cable under keyboard. I've also tried creating a bootable USB drive with diskpart with Prema and stock BIOS. If I press FN+B, the USB stick gets power, laptop shuts down, reboots and still getting the same black screen. If i keep pressing FN+B, the laptop just continues rebooting. Is there anything I can try next? This happened to me before, after installing latest beta drivers for Radeon 7970M. Laptop would not wake up from sleep and got stuck with blank screen. I left the laptop running when I went to take a shower, and when I got back it had booted up and worked fine. Only thing I noticed after that was that booting up to splash screen took very long time, but after that everything worked normally.
