Hi,
I don't know how computer technical you are, but it sounds like you knw a thing or two about them. So here's the best way to find the problem:
There could be many things that could stop the board from fully booting, Determining what is wrong is like detective work. What I do, is open up the case and take everything off the board to start. Then add the minimum to start a board to see if it will start. That's one drive (cd, harddrive or otherwise) the CPU, a graphics card (only if required) and one bank of memory. (which is not required, but it helps avoid beep codes) Also, make sure you have your pin's set on the board absolutely correct, or that could be your problem to begin with. If your going to load a ide drive, make sure you set your pin setting correctly on it, meaning the drive (IDE or EIDE) your putting on the board is set to Master, or Cable Select if your using the cable placement method.
Now, turn it on, and you should get the power supply on, and the cpu fan going. If they start, then make the next step to have the single drive be your hard drive, and see if it boots. If it boots, then great, open Bios and make sure Bios is reading the board and all things are fine with it. If so, what ever you put on next make sure it one at a time so you can identify what it doesn't like.
In the case where the CPU or power supply don't power up, it's then either one of the six elements. The CPU, Power supply, Ram, Drive, graphics card (if required) or the motherboard.
The next step is to replace each one of the first five, starting with the Ram Chip, put another like chip in and see the results. Then do the same thing to each of the remaining 4 components, the graphics card (if required), then the drive(cd, harddrive or otherwise), on to the CPU, and last the power supply. Hopefully something will show it's ugly way to make a change. Also, on the drive (IDE, EIDE or SATA) , try a different cable to make sure it's not that,
Now If no changes happen after all that, then I take it one step futher and usually get a like (doesn't have to be exactly the same, but a board that the components can be tested on) motherboard that I can test the first four, and make sure that they really work. If after that and you have tested all of the components and they all work, then it's save to say you have a bad Board my friend. It's a lot of work I know, but it's the sure fire way of finding out what isn't working.
 
Good Luck

Mark

Push power button and the power light turns amber and lights up then shuts off. the light in back of the computer is light green and it starts to turn on then dies


The fact that ity is trying to start and shuts off after ..it seams that it is the CPU fan to blame ...If the fan fails to start the CPU will turn the computer down instantly due to the temperature limit ..(in 1 or 2 sec ) ..
so ...open it up ..and see if the fan is spinning ...on start ..and if it is not ...check the connection with the board or replace it ..
(by the way ..this may also be a CPU failure ..and need another one ) ..

Computer turns ON but there is no display?


Drain it! You might be surprised that one day as you turn your computer on, it shows no display. It can be caused by electrical charges on the motherboard, I do not specifically know how it affects the display but in case this happens to you try to do a Power Drain. It's easy, first, take the battery out from the laptop and unplug the AC Adapter if it is connected(for desktops, unplug power cord from the CPU/tower) then press and hold the power button down for at least 30 seconds. plug power supply back into your system and turn it back on. There goes your display once again.

You should get it repaired. That is likely a power supply failure. Yes, I see you have power, but I still say power supply, because there are 2 types of power: There is Motherboard power and there is CPU power. If CPU power is not correctly flowing, the CPU will not activate. If the CPU is not active, the board will not process any information, even though the board is receiving power. Power supplies are not hard to replace and are usually about 40 bucks
