And it won't turn on. I tested each and every components in it. Practically new and works. Even double checked if every part is in the right place, checked if they're snugly fit, every connection in the right plugs. Please, I need help with this, I don't want my first pc to be a total failure. It's come to a point where even the LEDs don't light up at all. So I can't check the BIOS.
