Please help, Got my motherboard replacement, but Im having different problems now,

You sure when you reset the bios you put the pin back right or removed it? Plus pull your CPU 4/8 pin power connector off and make sure none of the metal connectors are pushed back into the harness. If you dont have the CPU power connector plugged in it will do exactly the same thing.

Plus do the same with your 24 pin motherboard connector, make sure none of the metal connectors are not pushed back into it to far

Sorry, I lost you, what you you mean ?

I've pretty much tried everything.
I've taken out the battery overnight and tried it while the motherboard was outside the PC.

1. For me, it makes sense that the Voltage varies when under different load, and I also heard it many times when I have been researching.

The voltage is only a small part of it. if you have a 60 amp/720 Watt 12V rail, it can successfully put out 12.1V @ 3 Amps and still be bad. It will pass a PSU tester like that too, as 99% of PSU testers test the V not the Amp/Watt. You need at least the V and Amp or V and W. amp*12=watt, so if you have one or the other, you get the other number.

2. I'm not going against my words. I've always said the same mate, I get a short single beep, which indicates a succesfull POST according to my manual, however I get no display. I've always said that...

BS. If you get a sound, your post test has found an issue. That aside, you can not say you have passed POST unless you get a picture of some kind. You can yet a single beep all day long and still fail POST, but the way you are saying it, you won't know as you say it is successful.

3.If it power's up the board, RAM and CPU, then what's stopping me from seeing video ? (I'm not using a GPU)Also, As I said, I just find it hard to be a PSU problem, as it has worked great until my first motherboard died. And worked fine when I had display.

Exactly. You find it hard to be one. You are joking yourself. Just listen to what you say here. "It worked before therefore it can not be broke now". You don't even stop to think that it could have been PSU all along. When they stop working they start breaking other components too. The Motherboard is one of the most sensitive components. But assume otherthings and just rebuild your computer unti lyou realize teh PSU is all that is left, as long as it floats your boat.

4. I have been in touch with the only Local PC shop in my area, They told me they would charge me £30 to test my PSU, and when I asked how would they test it, all they told me was they have a specialised tester to test it. That too me is just a PSU tester. Now I'm not happy paying £30 for someone else to do exacly what I can do.

Or it could be a watt/amp meter. You are assuming they only use a single tool, and are assuming that the PSU is not the issue. Test it yourself, but you need an amp/watt meter, and a PSU tester. Both of which you could have gotten immediately from the local hardware store.

Pull the 8 pin CPU and the 24 pin Motherboard power connectors off the board. Look inside them and make sure none of the metal connectors that go on the boards pins are pushed too far up inside and not making contact.

ahhh, OK.

Checked that and they all seem fine.

Wolfeking: According to the manual of my motherboard one short beep means succesfull POST test. Therefore, I believe I'm right to assume that my motherboard passes the POST test. THAT is not me speaking there, that is my motherboard manual speaking.

Also, I never said that "It worked before therefore it can not be broke now". I said, it powered my previous motherboard for 2 weeks great. And it powered my replacement motherboard while I got display perfectly. The way I see it, if the PSU was at fault when the 1st motherboard died, how could it start up this motherboard fine ? I'm not saying I'm right and your wrong here, perphaps you are correct. But from my point of view, it's most likely not a PSU problem

If you have another power supply? If so just set it beside the computer. Unplug all the connections of the installed Power supply. Hook up the backup supply 8 pin CPU and 24 pin, plus the harddrive connector, plug the backup one into the wall, hit the power button and see what happens.

OK, I tested the PSU and everything looked normal.

The -12 reading was 11.5, that was the only one I'm not sure with. Plus I'm not sure what is a PG. It read out at 310 on mine.

Otherwise everything looked fine.
