Computer Does Not Power On

A few weeks ago, I switched on my computer. It seemed to power on, then off immediately. After that, it would not power on at all.

Last night, I decided to try and figure out what the problem is with a view of fixing it. I plugged a kettle lead into the power supply and switched the wall socket on. Immediately, the fuse blew in the plug. I took out the power supply from the computer and installed another that I know works. This time it did not blow a fuse, but the computer would still not power on.

This is where I am at the moment. I think it's fair to say that the original power supply is broken, but not solely that. Is it possible that a faulty power supply has fried the motherboard? Unfortunately, the motherboard doesn't have a power LED, so I'm not even able to see whether it's receiving power.

Any help would be much appreciated.

"Is it possible that a faulty power supply has fried the motherboard?"

Yes that's possible.

Does the CPU fan start up when you start the computer, Sebby?

Thanks for your reply.

No, nothing powers on whatsoever.

Which fuse blew? - presumably the one on the PSU

Have you checked the fuse in the plug on the powerlead?

It was the fuse in the plug that blew!

Have you checked that the main power cable from the socket is okay and that the motherboard connector (from the PSU)is seated properly?

Yes and yes. ;-)

What type of computer (Make & Model)?

  Sebby 15:19 12 Jul 06

It's an eMachines 610.

It's a matter of working backwards from the wall socket, Sebby. If you're sure that's working, check the 'kettle' lead to the PSU, if that's okay, look to see if the power supply fan is operating. If that's okay, check the connector to the motherboard, if all those are working but the CPU fan isn't, then it's either a faulty motherboard connection or the motherboard itself is the problem.

Thanks for that. The cable from the wall is 100% fine, as is the PSU. So I can only think it's the motherboard. If it was the CPU or RAM, should the computer still power on?
