I learnt the same the hard way, I couldn't boot up past the motherboard

It was intermittent, but I never had a complete power failure. This lead
me to all sorts of difficult diagnostics and costly as I bought a new
mobo which the company refused to take back.

In the end after swaping out the memory and CPU with the wife's PC
eventually found the problem was due to the PSU.
Intermittent voltage on one of the input leads can cause this, doesn't
even need to be a complete failure which make diagnosis very hard.

You can get inexpensive PSU testers from dx.com. I have found them very
useful.
