I've scoured the internet for guides, troubleshooting forums, and even worked through the troubleshooting thread here on Toms Hardware but to no avail. I received all my parts yesterday and began installing the PSU into the chassis. This being my first build I didn't know what to expect. I unpackaged the Motherboard and found that the pins were crooked. After a few Google searches I took a needle and pushed them back into alignment myself, it didn't look bad at all.. Probably not the brightest idea of mine. I installed the CPU and RAM. Installed the Mobo standoffs in the case and carefully secured my motherboard against the IO shield and flush with the standoffs. Put the GPU in, required a bit more force than expected and worried me. Finished installing everything else.

Then the wiring process.
I followed the video to the letter. CPU power connector, 20+4 pin connector, Sata, Sata power, LED and Switches, Fans, GPU, Molex.

So when I turn the PC on, the LEDs come to life and the fans spin like they should. No display via HDMI however. And after about two minutes it shuts off and immediately comes back to life.
