Be sure to include PC make, model and details you think a repair shop may want to know about.
I turned on my computer a few days ago and the screen was black. All the lights and fans are on but they sputter and the off button does nothing. It was working fine when I put it to sleep that night but overnight something happened. I think there might have been a power surge. This is a custom built computer and I have already tried replacing the power supply, please help!
