This is what you do first: Take everythng off that mobo except 1 stick of memory and the cpu and heat sinc. When powering the computer on, check the keyboard and watch the LED's and If all three blink once and the CPU fan is running and you get the POST beep that the bios has loaded you are in pretty good shape. If that is sucessful, let us know and we'll go from there. Note: since it has onboard video you won't have to worry about the mobo giving you a long beep indicating that the video card is not installed. Post the results.
