My screen has for 3 years intemittently turned black and then 1-2 seconds later come back. Not sure if this is related or not. Today, I started my computer and it had 3 distinct bars of screen flickering. 

I have successfully updated the BIOS (which was a pain itself), updated NVIDIA drivers, updated intel drivers. I’ve tried random solutions from the internet that seemed unlikely to work in the first place. I’m at a loss of what to do now.
