Not even close

[The Vaughn]

I recently installed a dfi ultra-d, 1gb ddr gskill, and an opteron 165. I can't get it even close to booting. I bought a brand new psu. When I first installed it would turn on for about half a second then kill, I figured it was a card shorting something out so I removed all peripherals, after that didn't work I placed mobo out of the case, with nothing but ram, cpu, heatsink, and now it won't even turn on for the half second. 4 lights on the mobo blink for a split second when I first push the button, and absolutely nothing happens. I've built a few pc's before and all with minimal problems. Any help is greatly appreciated

edit: I'm using a really old pci graphics card, I've used it on other builds and it has worked fine.

First make very certain that your power button is connected to the power headers on the motherboard, it's very easy to misinterpret the diagram in the manual, I've been building systems for more than 12 years and occasionally I get it wrong on the first try heh, then power on with only the cpu and hsf connected to the psu. If that works add in RAM, then video then peripherals.
