This is usually the only sure way of finding the problem. But first, pull everything out except m/b, cpu, ram. turn it on. Do you get beeps? Try it again with a video card. What happens then? You could spend hours trying to figure out what might have caused the problem, but you'll never actually know what did until you start doing this sort of thing. You have to approach it with somewhat of a blank mind. No assumptions!

There is no such as thing as the only thing. It could be anything! I've had keyboards cause this sort of problem in the past, although it's less likely these days. I worked for a few years fixing PC's (among other things), and I learnt pretty quickly that you can't assume anything. Often a solution doesn't seem to make sense, but you when you see it work, you can't argue with it. 

Once you've found the problem, that's when you start with theories like cracked board, overheated CPU etc. Not before. otherwise you'll end up tearing your hair out!

On the other hand, the most common causes that I saw for this sort of problem were RAM, m/b or CPU (in that order).
