Thanks for all your help so far. So I've finally assembled together and......... the system won't boot.
When I press the power button, the system literally stays on for 0.5 second. The CPU & chassis fan spin for 0.5 seconds then dies.
No signal to video, no POST sound (do they still make beep codes in 2014?), nothing.
So I started to subtract parts and kept trying. No luck. It was stripped down to bare essentials below:
* AC cable into powersupply
* Powersupply cable into the motherboard
* The mother board is taken OUTSIDE of the case and resting on a cardboard box to eliminate grounding as the issue.
* The case POWER_SW pin connected to the mobo.
* DDR RAM & CPU (and CPU fan)
* Nothing else, not even video is hooked up (well it's onboard anyway).
Still same symptom... no sound or even a noise... just the fans & power 'on' light perk up for 0.5 second then it's off.
What's the problem here?
