I was playing a game and the screen suddenly went black. The keyboard didn't show any signs of life either. I tried all the system shortcuts I know, but nothing worked. Neither did the scroll/caps/num lock LEDs respond.
I forcefully restarted the PC and the screen went black during the OS booting process. This happened for both, Windows 10 and Linux. So I suspected HW, more specifically GPU.
I opened and cleaned the PC. When that didn't help I turned on the PC without any peripherals (including the graphics card). Connecting the monitor to the DVI port on the motherboard, I could see that the OS boots and shows the desktop. But when I tried to use the graphics card, the screen turned black the same way as before.
What exactly could be causing the problem? Why does the Graphics card work up until some time during the OS booting process? I assume that it happens when the OS switches from generic to the card-specific drivers, but I am interested in what might be causing this in hardware and why the system hangs and the keyboard loses power.
Also, this seems to be the same problem as in this thread (it has no replies though):
