Ok... I have...
Mobo: ASRock H61M-DGS LGA 1155 Intel H61 Micro ATX
Processor: Intel Celeron G1610
Got a cheap case+PSU from Amazon, but I've since swapped in a Bronze PS that I know works and am getting the exact same results.
When I turn on the computer, the ONLY thing that happens is the front power button lights up. No PSU fan, no mobo fan, no case fan, nothing....

Red = Connected to power supply (PSU is also connected to case fan + hard drive + dvd drive)
Green is the heatsink connecting into the Mobo
Blue is cables from case along with my SATA connectors (they are actually connected to the 2 SATA's to the right). HD Audio is the audio cable I have connected.
http://s7.postimg.org/z11iqntmz/Pic2.png is a close-up of the system header. I have the 4 groups of cables connected to the 8 leftmost pins as follows...
PLEDcolored - PLED White - Power colored - power white (top row in pic)
HDLED colors - HDLED white - Reset colored - Reset white - blank (bot row pic)
I've played around a bunch with those systemheader connectors to no avail. Help is 100% appreciated.
Thank you very much to anyone who has thoughts, experience, insight, suggestions...
