I built a new PC and can't figure out why it's not working -- even after swapping out many of the components. This is only my second build on my own so I may have done something wrong. I'll put the problem below, what I've tried below that, and then the build at the bottom. Any help/suggestions for what to do or how to diagnose would be greatly appreciated!
The problem: The PC turns on, but the monitor does not recognize that there's anything plugged in and remains off in power saving mode. The fans and lights on the GPU, graphics card, and the system fan all start up with the computer. The strange part is that the system turns on immediately when I turn on the power supply, without hitting the power switch. And the power switch will not turn the computer off. I have to turn it off by hitting the switch on the power supply. The computer makes no beeps or other noises beyond the typical sounds of a computer starting up.
Fixes I tried so far: I've tried using my old monitor, and the new monitor that I bought (in the build below). Both monitors work when plugged into a different computer. I've tried 2 different HDMI cords, and also tried two different graphics cards (the new card in the build below, and my old GeForce GTX 750 Ti). I've tried starting the computer with just my old hard drive, with just the new SSD in the build below, and with both. I've tried unplugging every peripheral. I've tried using the VGA display port on my old graphics card. I think I've tried some other stuff but that's what comes to mind now.
Current build:
