I don't think he is getting anything whatsoever on the screen...so going into the BIOS setup is out of the question.

I've had this type of problem at work on server builds when the CPU wasn't seating properly. Or worst case....was malfunctioning.

As far as the lights, it's normal for Gigabyte boards to light all of those up during the post...but when you get to the end of the POST they all go out. I was concerned with my new Gigabyte board when I saw all the lights lit...but it's like some sort of a system check.

Will when you purchased the coolermaster, was the psu already installed?
Was the mobo already installed?
The led pins were already connected?

I have two seperate micro pins marked +P LED and -P LED. there are 3 pins in that area of the motherboard. Should I just try them there?
Cheers, John

Adrian. The PSU and the case was a seperate purchase. The mobo, cpu (OCd) and RAM came as a bundle with the Noctua HSF which I had to install and the mounted the mobo in the case. J

You're right pp I'm getting nothing on screen at all, J

John, from your responses this is a barebones build so my area of concern is the small micro pins that are attached from the cooler master tower and then connect to your mother board.
They must be connected from the tower to the mobo in the correct position. The pins are marked with very small tags, the led sockets are marked the same as the tags but are very small. They will be bundled and are already connected to the front panel of the tower.
Off the top of my increasingly small brain:) 1 would be marked power, 1 would be hdd sound, 1 would be marked HD etc.
These exceedingly small pins are often overlooked, how ever if they are not connected and in the correct positions on the mobo the system will fail to do the initial post.
Im attaching a representation of a generic cooloer master and your mobo so you have an idea of what to look for.
Regards,
Adrian

When I built my computer, I was in the same position and looked around the net etc for a answer, my probem was I missed one connection from the cpu (and missed it like 5 times redoing all the connections) It was the power for the cpu, it wouldn't post or anything without it, just start up to a black screen. Might be worth a try to look over every connection you can in case you've missed something.

One thing that I do find is that when you have been trying something for a long time the best thing is to simply take a break.

Give yourself an hour or so away from the problem - find something else to do for a while - something totally unrelated to PCs.

After the break re-start from scratch and often the error being made (assuming there is one ), will not happen.

John, take an hour then go back and as suggested above re-make all the connections exactly as you have done - it's worth a try

Adrian. Just had a closer look at your pic. I don't have anything plugged in there. Only the power switch in the pin enclosure to the right of that in your photo. J

That indicates that you should have the Hard drive pin connected, the sound car pin connected etc.
Since these pins are not installed on the mobo there is a strong indication of Post Failure.

Look at your mobo manual and look at the section where it covers LED connections. remember that these LED's refer to your tower led's not the mobo's led's.

Adrian

Adrian. It looks like we have the same case. Heres what I have in terms of double strand small female sockets-
Double female marked power switch
Double female HDD Led
Double female reset sw
2x Single female marked +P LED and -P LED.

I will take some pics of the area close up and post them.
I only have the power switch cable in ther right now and it is in the red area within the little enclosure at the bottom as seen in your pic. This contains a little yellow area with two pins, a red area with two pins a gap then an orange area with four pins. On the bottom row within this little rectangle there is a blue area with two pins, a pale green area with two pins and a brown area with one pin. So thirteen pins altogether.
Immediately to the left of this is an unenclosed area marked PWR LED with three pins in the top right.
As I say, I'll try and take some close up pics and post them.
Thanks very much for your help, John:)

I presume I have the power switch in the right place as it works.J
