Display issue, screen turning on for a while, then goes black.
Further down the road since I originally posted this;
I opened the computer, installed a new HDD, vacuumed out all kinds of dust and unplugged the vents, both by the blowers and also air intake at the bottom.
Now the screen stays on longer, sometimes even for a whole hour. But it still does shut down intermittently. I did the flash light shining into the screen, and indeed, my stuff is still there, but very dark. Any informed guess at what this means?
Is this a good question?
