Re: WinXP BootScreen loads... then Monitor goes blank/standbyes
When this happens it is a sign of a hardware fault. It's not necessarily the video card. You say he just networked his pc. Did he install a network card to do this?? If so then try booting without the network card present. If this isn't the case then the only thing to do it to remove all cards except the video card and see if it boots. If it does then it's just a case of replacing the cards until you find the culprit. If it doesn't then try taking the video card out and reseating it.
If still no joy then check all cables are connected properly.
Does he get any beeps when booting???
