Does the heatsink get hot to the touch?

Must admit that I also suspect the CPU too.

So, any change?

HIPRO isn't a known quality make. Not sure if the PSU is the problem tho.

18amps sounds right.

Remove your ram and make sure the edge connectors are clean then remove the CPU and check for bent pins.

Unplug the hard drive and see if you get a different error message.

Can you remember what make the original PSU was? Was it Bestec by any chance? If so, I would suspect CPU and possibly ram damage.

It wont stay on for more than 2 minutes so it's not the hard disk or the operating system causing the problem.

The very first thing to do is to give it a good dust out. I use a cheap 1 inch paintbrush for the job personally.

Are both sticks identical?

Nope! It's not possible if it shuts off while installing from your windows cd.

One thought occurs. The ram sticks, do they have any labels on them showing their speeds?

There is something very seriously wrong with your system, you may well need to take it to a professional.

In that case you may have faulty ram. Google and get memtest and run it for at least 7 passes. If you get any errors at all then your ram needs to be replaced.

The external will make absolutely no difference at all. You probably need to boot from your windows CD and do a repair.

Try safe mode.

Atx 2 should be fine. It should only plug in in the correct position. If you are worried, you can also get an atx2 to atx converter.

That does indeed sound like the data cable.

If it looks like that then it should be plugged in to your hard drive provided the hard drive is also...

I would say the PSU is faulty. I am one of the few that can repair them so I know what I am talking about.

+12V was 11.31V = bad.
no -5V pin from the psu = bad.

You either have a dodgy data cable or a dead hard drive if it does the same thing with 2 mobo's. A new data cable will be the cheapest thing to try.

I recon removing and refitting everything may be an idea, including all cards, ram, and CPU.

You'd be surprised where dust can work it's way into to cause problems. If you need to remove any dust...

Unless the new mobo is identical to the old one, it will need a new windows install anyhow.

What about my second question?

When you say it doesn't beep, are you sure a PC speaker is actually connected?

Did anything happen when the problem started like the PC being moved about or a power cut?

Try resetting the bios. INSTRUCTIONS (http://www.wikihow.com/Reset-Your-BIOS)

Well I use an eye-t 450watt PSU that was only £25 brand new and it's been fine for over 4 years now if that's any help.

Sounds like the hard drive may have had it.

I would suggest testing the voltages of the PSU. You must have heard about all those E-machines that died, they were all fitted with the Bestec 250watt PSU. There are now tens of thousands of them...

Safe mode or las known good configuration may be worth a try. INSTRUCTIONS (http://www.pchell.com/support/safemode.shtml)

Try clearing the cmos. Your mobo manual will show you how to do it.

Just a thought before this thread is forgotten, did you remove the driver for your old graphics card before installing the new one?

Absolutely! They are expensive to buy and even more expensive when they go wrong!

Undoubtedly! :) I was just pointing out that Sony are too cheap to actually supply a windows cd.

It's a Sony Vaio so it wouldn't have been supplied with a proper windows cd.

If you have a digital volt meter you can test the PSU. I can supply you with instructions if you want.

As I said, shorting the 2 wires will make it turn on, unless it is faulty that is. Green is ps_on and black is ground.

All that yellow light means is that the 5volt standby is working. It means...

You need to unplug your PSU from everything then short the green wire in the biggest plug to any black one with a short length of wire, the PSU should spring into life. If it doesn't, it's dead and...

It's just a shame I didn't have better news about your Sony.

No idea. I have never shipped anything over the pond. There is also the problem that this machine is set up for 240volts, not 110 unfortunately.
