I just bought a barebones pc from tigerdirect. I installed everything correctly to my knowledge. At first, the PSU wasn't showing any signs of power at all, so I tried the paperclip trick and the fan started working. I have already tried unplugging everything and going one by one. No lights, no beeps or anything.
