I have an Asus P8H61-M MB. Intel i3-2100 CPU and 4G 1033 RAM. I have put together many computers from scratch, but can't figure out what I'm doing wrong with this one. When the power button is depressed the Power LED lights upand the CPU/Chassis/PSU fan all start for a split second, and then power dies out.
I've tried flashing the CMOS but to no avail.
