Hi,
Thank you for taking the time to read my post.
The board wont power on. Is there any way to tell if the board is getting power?
Friendly Regards

Is the CPU fan spinning up.....any LEDS..........Odds on there's power

No the board does not power on. I was trying to find a way of determining what the problem is, I've tested the PSU and it works. With my DFI lanpart board for example an orage led lights up when you plug in the power even with no components, I wanted to know if the gigabyte motherboard had the same or not. I'm not sure if I should buy a new case or not to test the motherboard.

If your sure the board is connected up properly........sounds like it's toast for some reason.
Do you have access to a shop or friend with equipment that can confirm the board is DOA... ?
It's a bit hard to fault find over the forum if it can't even power up with a good PSU.... do you agree!

Yes thats the problem I face is that I can't judge if its broken or not.
The PSU is a "be quite! pro 750W" and I have plugged the main ATX power plus 4pin addition in. Then I plugged the P4 12 volt CPU plug in.
I don't even know things like if there is no CPU and RAM will the board power on for a short time and will the PSU fan spin as a result?
-
I'm going into to town to buy a power switch alternative to eliminate the possibility of it being my case.
What I also need to know is if the board would show signs of power even if I had faulty components like CPU and RAM, can I get an indication of workingness without those components inserted.

Hi
I really don't like these Be-Quiet PSUs and just wanted to make my standpoint clear. I wouldn't be at all surprised if it is the problem but a short to the chassis from the motherboard would give you the same symptoms. I would advise doing this:
The next thing is to remove the motherboard from the case and test it on the workbench.
Make sure that you observe anti-static precautions.
Lay some cardboard or use the motherboard box that is non-conductive on the worktop and remove the motherboard/CPU/heatsink/fan/buzzer/one stick of memory and PSU from the case and put it on the cardboard. Add the keyboard and now I know you haven't got any graphics but try and boot. The system should try and then fail emitting a series of beeps. Please post what sounds it makes.
This video shows you how to test a PSU easilly. Shame Corsair used to have a much better one on their website but it has been removed now.

This board comes with onboard graphics based on the intel CPU.
I will try the steps you suggested.
Would it be worth buying a PSU tester for £19 which has leds to indicate power but does not tell you load?
I've just acquired separate power switches and power led's just incase it was the case.

With my new loose power switch and the instructions above the motherboard booted and appears healthy. I will post a video for those who read this post and have had similar troubles.
Great community help, thanks.
and here it is:

Yes thanks for making me do that, you saved me a lot of hassle.

Presumably it was a short to earth via the chassis then. Check out the motherboard standoffs as this is the most common of shorts to be found. Either too many or one in the wrong place.
-
Not this time, it was the power button on the chassis. The lights flashing on the PS2 keyboard helps when checking if things have power, forgot about that one.
Turns out putting a jumper on the power supply button/sw or trying to complete the circuit did not work for me this time round, i needed a working power switch to resolve the issue.
-
Great you got there in the end with a definitive ..........."GOTCHA!"
It's always with 20/20 hind sight all the little tricks come back in your memory........on the motherboard front panel header, there's one pin in red marked power..if you short this pin with the one directly underneath it .... this will do the same as a connected power switch......to turn off I usually just hit the wall switch..........not the most elegant power down, but fine if your just testing

Some of these cases are fitted with really cheap crappy switches which is stupid considering the price differential between them and a decent switch.
If you were shorting the correct two pins the board should have started if done properly as that is all any momentary switch will do. Anyway main thing is that you found the problem. ;)
