Windows updated a while back and it crashed my computer, when I went to start it back up it keep restarting over and over again. Eventually nothing showed up on the display. I decided to open it up. When I turn on my computer everything starts up, the PSU, GPU, and Hard Drives, but nothing shows up on the monitor, not even the bios for the motherboard. I personally believe that this is fault to the motherboard or the cpu, but I don't know which one. Any help wold be appreciate on figuring this out.

I've tried that. I even tested the GPU and hard drives in another computer to make sure they were not at fault.
