Please please help!
I recently installed a new socket 478 motherboard in my 2ghz P4. Everything went well until i tried to install a video card. Then the pc wouldn't recognise the hard drive. I figured this was the psu and got a new one but computer wouldn't work with the new psu and video card. I then put the old psu back in the pc and it booted up to windows but shut itself down. I have taken the video card out but now the computer won't start at all. when you turn it on the fans and lights start for a few seconds but then it shuts itself down. i can't plug in the internal speaker as it is not compatible with my new motherboard so i can't diagnose anything from beeps on start up.
