New rig won't POST!

Cheers Nigel, I'll take the dog a quick walk and the start over, J

Led connections

John, as Nigel suggested: Take a break and take the dog out for a stroll
Come back to it and connect the remaining LED pins.
Again I use strong caution here, the pins are small and very delicate use gentle pressure when you complete installing them.

Hi there
I've had something like this in the past.

1) At power on does the CPU fan stay on or even start.

2) I found on some mother boards you could only get the system to work by connecting the power switch and power led in the mobo to the connectors in the case and then pressing on the RESET / Power switch on the case. If you did't do this or didn't have these connected the system would NEVER power on at all so no post possible.

3) the Auxiliary CPU power -- is it a standard 4 pin one or one of the newer versions with more pins (most older boards have the 4 pin connector).

If you've got the wrong one or haven't plugged it in then no go.

4) Take EVERYTHING out of the mobo apart from the CPU and the video card -- even the memory sticks and keyboard and see if at least the machine will power on properly (Fans whirring and CPU fan starting).If you have an onboard video card make sure you haven't disabled it if you are testing without using an external video card. If you are using an external video card disable the onboard video.

Even if you have an external card I would still test with the onboard video if the board has one first.

5) add keyboard and memory slots one at a time -- you should at this stage see something of a BIOS message even with 0K of memory installed.

If you get 5) working add peripherals in bits until whole system is ready.

Don't do any fancy overclocking / adjustments until you've got some type of decent BIOS Post messages..

If all this fails then the chances are only one of 2 possibilities

1) the CPU is incomaptable with the board -- happens more than you think

2) CPU / Motherboard is defective -- the CPU's are actually far more rugged than you think and with Zero Force Insertion its unlikely you've got damaged pins etc so defective equipment is not normally likely -- I've built loads of machines over the years and NEVER had a broken CPU. (I've dropped them / mis treated them etc -- never had a problem).

Motherboards are sometimes not compatable with memory / cpu but that's another problem.

Cheers

Well I had a walk with the dog but failed to take mind off this build. Here are some pics of the area concerned and the micro connectors I have also the black and white cabled connector that comes out of the psu with the main bundle. This seems to have WST 34 written on it. Think I need new glasses for this job.

This is the mobo pins:

 

[johnwillyums]

And here are the connectors I have. The second one is the one that comes off the psu:

The black and white connector on the right is an RPM fan control for the fans in the power supply unit. You can see it right at the top of this diagram

Jimbo. Good to have you onboard.
1)Yes the CPU Noctua HSF comes on and stays on.
2)Haven't got to that stage yet as I'm unsure where to stick the connecters. See above.
3) Don't know. Which is the Auxilliary power. Wherever it is I don't have it connected
4) I've tried that apart from removing the RAM and ,yes, it powers up.
5) I've tried all sorts of combinations. I was at this 12 hours yesterday. Everything powers up in the case except my GTX 260. That shows no sign of life at all. I swapped it out for my old 8800 GTS 512 and that powers up, fan spins etc.

As I said in my op the mobo, cpu, ram and Noctua HSF came in an overclocked bundle (i7 [email protected]) and have supposedly been thoroughly stress tested for 24 hours so I don't think they are incompatible.
I just don't know how to connect it all up.

Thanks for your input, John

I have the same MB.

Look in your manual. Page 27, F PANAL (front panal header) this shows where the connectors go. You will notice the speaker pins, this is for the MB speaker that beeps on startup. Once you have the speaker installed you will get beeps that will help you trouble shoot your startup. See page 99 for beep codes.

Hope this helps.
Tommy

Ok, in looking at your connections on the left;

The hard drive LED goes into the lower left 2 pins in the block. Generally speaking, the colored cables are the positives...while white and black are usually the negatives. Thus the blue cable for the HDD LED should plug into the first pin from the left.

The reset switch is just to the right of the HDD. The positive here in the purple cable. Thus, the purple connection should be in the 4th pin from the left.

The power switch goes right above the reset switch into the upper row. The red cable is the positive end. Thus it should go in the 3rd pin from the left.

The two power LED connections go onto the block of 3 pins between that F Panel block and the first yellow USB block. These cables are labeled + which is the blue one and - which is the white one. You will have to look at your motherboard manual to find which of those 3 pins is positive and which is negative. One pin will go unused.


As far as the speaker goes...it's possible that your case will not come with a PC Speaker. My latest case, the Antec P183 did not come with a case speaker. So, those pins are unused on my mobo.

Antec maintains that many new mobos come with speakers built-in...so hence reason they don't include speaker with case. If you have a need for it...most case manufactures will send you one. Or you could get one 3rd party as well.


Unfortunately, I don't think these connections are your problems. Typically if the power switch is wrong, pushing the power button or reset does nothing. If the LED's are backwards, the lights will either be on solid or will blink at exactly the wrong time...but won't prevent the machine from running.

I truly believe you have a CPU problem here. I'd remove it from the board and attempt to reseat it. Otherwise, it's possible that your overclocked CPU has a problem...and hence reason I don't usually recommend buying a machine that is pre-overclocked.

Thanks Tommy. So all the connectors shown in the first picture above go within that box? Apart from the red area which I used as power switch it's not clear where I put the others.
Also. I can't see what you mean about speaker pns and don't seem to have a speaker connector. What does it look like?

Thanks for your help, J

 

[pparks1]

No, go read my post. Everything goes within the box with the exception of the power LED...which is just to the left of the box between the box and the first yellow USB connector.

Also. I can't see what you mean about speaker pns and don't seem to have a speaker connector. What does it look like?

A speaker connection would be a 4 pin black connector just like all of the others that you have. It would say speaker or SPKR on it. Since you don't have one...don't worry about it. You just won't use any of the 4 pins that are showing on the upper right side of that block.

 

[Tommy]

Go ahead and install your connectors, we may not need the speakers. If it doesn't work first power on press your reset button sometimes this will turn it on.

Ok. I've connected as you have suggested pp. I'm getting power plus 2 LEDs on the top panel of the case, The reset button is not working (the power button is and I can do a hard shutdown.
Do you think I should connect up my monitor and see if it posts?

Thanks, John

Yes, by all means try. If the reset button continues to not work, reverse the connection of that plug. It's possible it's labeled wrong or mobo is wrong.

 

[johnwillyums]

Well I reversed the reset button but still nothing. Tried it both ways a couple of times but no luck.
Going to connect the monitor and try to post. Back soon, J

Hi Folks.

I've had a POST!
I connected up the micro connectors according to pparks outline and got LEDs plus power but no reset.
Next I found and connected the auxilliary 12v power cable at top left on the mobo.
This reasulted in a post screen plus an overlay box about boot fails and settings and press any key to continue. This didn't work so I don't have a keyboard or mouse. Both are usb devices and my Kone mouse is very temperamental about drivers.
I tried the reset button and this time it worked and I got a Gigabyte splash screen but this failed after a few seconds.
So I seem to be going in the right direction. My friend is bringing over an old psi mouse and keyboard so I'll try that.
Any further guidance most welcome.

Cheers, John

 

[johnwillyums]

Well guys I think I'm well on the way. I installed my 1TB drive from my old system and booted into W7 (still have dual boot choice)
I'm using a psi keyboard amd mouse and haven't sorted out all the cabling inside and the system fans.
Curiously, I daisy chained the three large system fans together and they all ran but I lost the LEDs on the mobo and my internet connection so I must be doing something wrong there. Any help with that would be great.
It's weird that fans should disable the motherboard and cut the connection. I have to have the fans and intend installing a further 4 Akasa Apaches inside bit the big 10" system fans are pretty crucial and I can't see any other way to power them.
I'm much happier now that my machine lives and I couldn't have done it without your help. It's bedtime now but I'll be back tomorrow with further problems no doubt but I think I've got past the worst

Once again a thousand thanks, John

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.

Forgot to thank you for your help Kawaii and most importantly forgot to welcome you to 7forums.
Great place and great people as you can see

 

[profdlp]

Lots of good advice and very patient help here. I'm glad I read all the way through to the end before I tried to post any suggestions of my own.

I have the exact same basic rig as far as CPU, MB, and RAM. Once you get it all set up you are going to absolutely love it.
