I built my own computer last summer and it overall runs very well. I am having one problem: sometimes, it won't turn on. I have a case that allows me to see inside through the side panel, so I can see that when I turn on my surge protector to the computer, the green light on the motherboard doesn't turn on. It isn't getting power. Eventually (after turning on and off either the power supply or the surge protector) the green light does come on and I can turn the oomputer on. Once on, it runs fine. However, it just doesn't like to turn on. Usually when I first turn on the surge protector, a fan will start. On subsequent tries, the fan doesn't turn on. Power supply problem or something else?
