I've been trying to build this computer for my girlfriend and it won't start. Every part is in the right place and the wires are where they should be but whenever I try to start it up the light for the graphics card and the case fan start for a split second than shut off. I've tried unplugging parts and starting it up but nothing seems to work. I unplugged the motherboard as well and it wouldn't start up for a split second. There are a few bent pins on the back of the motherboard I just wanted to know if that is causing the issue.
