Hi all.
First off I have to say I'm an IT pro who started in the business building and fault finding PCs. (1st gen Pentium processors). This is my home PC.

In short; Motherboard won't boot; it powers up then stops, powers and stops. Video here. https://www.youtube.com/watch?v=HGy5-wAwy4o&feature=youtu.be

As you can see it's barebones on a wooden floor. I've seen this behavior before when there's no CPU fan present but there deffo is and I've swapped it out.

I've also swapped out the PSU. I've taken out both RAM sticks all making no difference.

So it's the motherboard. But this is the 3rd motherboard in 6 weeks.
Original long serving Asus motherboard went the same way. Swapped for another the same model. This replacement Asus motherboard went the same way a week later.

Swapped for an ASRock. This ASRock motherboard has gone fubar too.

Possibly an unstable PSU giving too high voltages at random?

I've not changed the CPU (Intel i5 3578K) at any time. I do have access to another but seriously doubt that's the cause.

Assuming I'm not being voodoo'd any suggestions?

I'm just sitting here wondering how long it's going to take you, a self-professed IT Pro, to start testing the other components, especially the PSU? :)

There comes a time in the life of some systems that some gremlin eats so many spare components that it's probably not cost effective trying to do the time-honored trick of "repairing by replacing".
