Press the power on button, the PSU fan spins for a second so does the CPU fan but both stop. The motherboard has a small amber led labelled 'DIMMLED' which I know is something to do with the memory (although I would think a memory problem would result in bios beeps...)
anyway, that led stays on but everything is dead...
If you hold in the power button the led will go out as if forcing a hard reboot.

My thought is the PSU...any other ideas...?

If it was something to do with the mobo would that stop the PSU fan?

What is everyone's thoughts?
