Hi All

I have been given an old 'broken' PC by a friend. He says if I can repair it, I can keep it!

Here's the details:

One day, he tried to boot it and nothing would happen. When he tried to boot the fan comes on and the hard drive spins etc, but nothing happened on screen, just a black screen.

The machine doesn't even seem to reach the POST, and you can't get into the BIOS or anything.

I've opened it up and had a play around, but I get the same problem. The Motherboard speaker clicks twice, like:

click-click............................................. ...........click-click.........................................clic k-click

I know this is the motherboard speaker and not the HD, because if you remove the speaker, it stops!

Reading other forums etc, this is what I've tried:

1. Tired removing RAM and booting, same prob
2. Removed Graphics card, same prob
3. Removed HD, same prob. Can access the drive fine as a slave on another machine.
4. All of the above in different combinations
5. Replaced the motherboard - ASUS P5VD2-MX, still same problem.

Other forums have suggested that it might be the PSU, but it does power up the MB, HD, CD and the processor fan etc, so it is working. I thought maybe it wasn't producing enough power any more, but in my (fairly limited) experience, PSUs tend to work or not.

The only other thing I can think is that the processor is fried.

I really want to know if there's any way I can find out what is wrong with the machine, whether it's the PSU or CPU? Unfortunately I don't have any spares of these 2 things to try. I've taken apart every PC in my office to find a PSU to test with, but I can only find a 280W and I need a 450W.

I suppose the Graphics card could be dodgy and the onboard disabled, but I don't know how to check this..

The 2 clicks must mean something, but there's nothing in the MB manual or anywhere I can find on the web to tell me what the problem is.

Anyone who can offer any advise, would be my friend forever!!

Cheers

I would say PSU. Dead PSUs commonly power up the PC partially and they are also really unreliable.

you can still try the 280 watt psu, if the computer only has a hdd, cd, standard graphics card ect then a 280 watt psu will be sufficent to test the computer
