Just built my first system in a long while, and it has not resulted in immediate success!
All of the fans come on, along with all the case leds etc, and the hard drive activity light flashes on for a moment, with a solid light on the motherboards led. There are also no error leds on the mobo (so grfx is installed properly), and the grfx fan is spinning. However, the screen displays nothing (just a message about check the connection), and none of the capslock etc leds on the keyboard will respond. There are no beeps issuing from the motherboard, so I can't check the manual to see what is wrong.
