So I built my first computer. But, when I try turn it on nothing happens, other than the fans twitching (one fan in the PSU is going, nothing else). I googled, and it sounds like the motherboard might be touching the case. But I've checked, and can find nothing wrong. I re-did all the wiring, double and triple checked it all... still nothing. I don't get it. I built it on a table and kept touching the kitchen tap to ground myself, but I guess there's a possibility that I messed it up with static... Any idea how I can fix this? There is a computer shop in town, but it's a bit dodgy imo..
