Help! - Computer Will Not Power Up

ross1204 · 08-06-2008, 06:09 AM

Hello,

I have recently been asked by a friend to re-format his old PC but I have now encountered a problem which I can not seem to fix.

During the formatting of the hard drive we left the room as being an older machine it would take a bit of time but when we returned to check up on how far it had progressed the PC had now turned itself off.

I now can not power up the machine since this strange shut down. I have tried plugging it in to another power socket which did nothing. I then tried a different kettle cable (power cable) which again did nothing at all. I then tried checking all the connection of the components and connections to the power supply which all seemed OK but again this yielded no positive result. The last fix I tried was to replace the old power supply with a spare one I have which after installing and testing again did not power up the PC but for a brief second the heatsink fan spins.

I really cant understand why the machine does now not power up anymore.

Does anyone have any ideas on what the problem is and how to fix it?

Thanks

Ross

hey ross,

unplug the computer and unplug the bios battery.

if it still doesnt work after unplug the hard drive and any pci cards you may have, just unplug everything that isnt nessory

Thanks for the quick reply.

I've unplugged the bios battery and non-essential components and still nothing. As the heat-sink fan rotates for a brief second then stops would that imply fault circuitry and the only real option is to replace the motherboard? But also I take it if the motherboard has blown there is a chance other components have also?

Thanks

Ross

try another psu, if that doesnt work it sounds like the pc has gone

yeah as I said in my original post that the last thing tried and didn't work, I'm thinking motherboard has blown due to old machine buts its a real coincidence that the hardware went right when I was formatting the PC.
