The computer I built in 2002, running XP Home started to give me a lot of problems and after trying verything I could to solve them, I gave and started looking for a new mainboard. After talking with an upgrade company, they told me that they could supply a new mainboard that was compatible with my Gigabyte GA-7VRXP so I ordered it. I fitted it, along with new memory and an empty formated hard drive to re-install XP. When I press power on, it starts up normally for about 5 - 6 seconds and then powers off. This is too quick for anything to appear on the monitor. Ive checked and rechecked the front panel connectors which are mostly plugged into one 9 pin panel and I can't find the cause. Do you have any idea what might be causing this ? The new board is an ASRock K7S41GX. Im really depressed about this. Ive built 3 computers before without any problems.
