BTW mods - go ahead and move this to Homebuilt if you like... where I should have posted this
I recently assembled my first build. Everything seems to be seated correctly (I've checked and rechecked). When I power the computer on, the fans run, leds turn on, and I can hear that the hard disk is spinning as well. However, when I plug in the monitor via DVI, it doesn't turn on with the computer. If I try to manually turn on the monitor, it just displays a 'no signal' message on the screen. When I plug in a keyboard/mouse (which I have confirmed work) into USB ports they don't seem to have any power (since the capslock light and mouse's laser don't light up). This applies to ALL of the USB ports, on the mobo itself and on the front panel. The only thing the mobo seems to be doing correctly is running the CPU fan...
I tried clearing the CMOS; no change.
My hunch is that the mobo is dead, either on arrival or because I screwed up somewhere along the line.
