Just put an AMD 64 3000+ CPU on an Asus 8KNE-Deluxe with a Thermal Take 360 W PSU. I push the power button and the PSU fan starts to turn, the CPU fan starts to turn, then nothing. It will "start" when I push the button, then quit.
I am suspicious that the 360W PSU isn't enough for the rig - I unplugged all my peripherals (hd, cdrom, video card, etc) to reduce the power strain, but still the same thing.
Any ideas?
