OK... here is my situation. I recently returned from a 15 month tour in Baghdad. As a reward I decided to buy myself an extreme gaming rig. I had previously put together a lower end rig with help from a knowledgeable friend so I figured I knew what I was doing and I could build it myself. Obviously I was incorrect. I unpacked all the components for the tower and went to work following, as best I could, along with the provided literature. I installed the motherboard, PSU, optical drive, HDDs, video cards and RAM. I connected all the power cables. This is where I felt I was screwing up. Everything looked ok so I decided to try and fire it up so I could check the BIOS and all that jazz. When I flip the switch on the PSU I get a blue indicator light on the motherboard. When I press the power button on the case fans spin and LEDs turn on.... but only for about half a second before turning off again. I've gone as far as disconnecting all the drives and check my power headers. I tried removing the USB headers with no change. I'm at a loss. Here is a list of the components I'm using: Motherboard: nForce 680i SLI CPU: Intel Quad Core Duo Extreme PSU: OCZ 700w GameXStream RAM: 2gb Corsair DHX XMS2 Dominator Video Cards: PNY GeForce XLR8 8800 GTS 640mb (I have 2) HDDs: 150gb WD 10,000rpm & 500gb Seagate Any insight anyone has will be greatly appreciated. I have a feeling it is something relatively stupid and obvious. Thanks.
