I'm putting together my first build, and have a somewhat unusual problem (at least, the googling I've done hasn't led me to any similar situations). I've assembled everything (I can provide specs if that's necessary). When I switch on the power supply, all the fans start - power supply fan, case fan, graphics card fan, cpu fan. However, when I try to power on (I haven't hooked up the power button yet, so I'm just bridging the two pins on the motherboard) nothing happens. No change in fan speed, no POST beep, nothing. I've gone through all the steps in your lovely troubleshooting thread, and it has changed nothing. My assumption is that my motherboard is bad, but I wanted to get a second opinion before I send off for another one.
