A friend of mine had a similar problem, where his computer only booted on the second time, but did so everytime. Try updating or reinstalling the BiOS, that's what fixed it for him.

i've had issues like this when i was building my com as well, ended up being the BIOs.

Go and try updating the BIOs,if it's already up to date you can try reinstalling it.
