Did this problem recently occur? If so, what happened prior to the problem?

Has this system ever worked for you?

Hi, thanks for replying.... :o

The computer worked very recently, perfectly. Then It stopped working!
The previous owner tole me this and then he had sent it off to the repair centre to get checked out...
They said that it was going to cost over £500 to fix, so he gave it away! To me :mrgreen:

Anyway, I have now isolated the problem at the Processor or the motherboard!

I took everything out, leaving just the processor, mobo and Power Supply in. So I tried to run it and no front lights came on but the fan was spinning away!!

It has an on-board graphics system so that's how it could work! I also tried it with a PCI graphics card but same effect!

(I left a 256mb Stick of DDR RAM in it )

So it looks like the Proc. is dead

Possibly, possibly not. Use Everest Home Edition to identify the motherboard in your system, visit the manufacturer website for the motherboard and download the motherboard manual.

Check the front panel connectors to ensure they are attached correctly.

mmmm, but the computer doesn't start up, How can I identify It??

ooops! Silly me!

Open the case and see if you can find any identifying markings on the motherboard. (Look for a make and model number printed on the board itself, not the markings on chips that are fitted to the board)

CPU is more likely fry can't say it the motherboard because it power everything on.You can get a p4 cheap nowadays
