Hi,

I am building a new PC with an ASRock A520M-ITX/ac

The problem is the PC wont start at all.

However when I remove the CPU power cable from the motherboard and the fan does run.

At first I thought it might be the power supply... but I checked the CPU supply cable and it is producing the 12v on all the necessary pins.

The only thing I can think of is the motherboard manual doesn't seem to say what slot I should put my single 32gb ram stick into... does it matter?

Thanks,
Matt.
