One day, out of the blue, during a zoom call, my computer screen went black. I knew power didn't go out because my keyboard backlight was still on, and that was receiving power from the USB. I touched the spacebar after about 20 seconds and the screen came back to life, though I had to reconnect my zoom conversation. But then after about a minute, the screen went black again.
I tried restarting the machine, but even after a restart, the screen will go black after anywhere from ten seconds to a minute. Not sure what the problem is. I restarted in safe mode and went through some startup items getting rid of them, and that seemed to fix it for a day, but then it went back to blacking out, and it even blacks out in safe mode. Any ideas?
