I have turned on my PC twice today from cold, and both times, it has failed to POST. after forcing a reset, it successfully POSTs and completes the start up procedure.

I'm trying to figure out the likely cause, but don't know where to start.

any suggestions?
 
Sounds like the motherboard is not getting the power it needs from the PSU.

How old is the machine/PSU?
 
Hope you've got everything backed up safely!
 
do you hear any beeps from the motherboard when you power it on? If you do i would refer to your motherboards manual to find out what the beep code means as it could be a few things causing this, lack of power as cokker said, memory, cpu, GPU to name the biggest ones. You could try re-seating the components i mentioned to make sure its not one of them having an intermittent connection, however these would usually produce a beep code.
