Yesterday was a long day installing all the components into my new computer, which took a good couple of hours (I had to make sure I did it properly). Once that was done, I excitedly turned it on, and after spending a minute or two in the BIOS changing some settings, it just powered itself off! I can tell you, the feeling you get in your stomach when that happens isn't nice. So after playing around a little, checking cable connections etc. I turned it on again and took a look at the hardware...
