Question Turn on computer, everything starts as normal, but screen is black.


Jun 11, 2017
When I turn on the computer everything starts up almost as normal (I've noticed that it whirs up for a second, pauses, and then carries on, which it didn't used to do). However, the screen is black, nothing happens. I've changed the PSU for a new one, and replaced the Motherboard, but the exact same problem is still happening. I've swapped out the Graphics card, and tested my HDMI cable on a laptop, all to no avail.

I'm absolutely stumped now and have no idea what to do next, the only thing i haven't changed is my processor, could that be fried?
