[ale] Have a hardware question on no POST

[Ted W.]

It sounds like either the CPU/memory is not seated correctly or the PSU 
is not providing enough power to some part of the system. I've seen this 
behavior from systems when I forgot to plug in the 6-pin 12v rail to the 
discreet graphics card. I've also seen it when the PSU was not supplying 
enough power to the connected devices (eg. old 400W PSU while using a 
discreet card w/ minimum power req. of 400W).

Since you're not using a discreet card and everything else on the system 
is new. Assuming it's all seated correctly I'd check the outputs on the 
ATX connector and the 4-pin 12v rail (going to the motherboard) with a 
multimeter and make sure they're supplying the rated voltage and amperage.
