New PC build - MB fails to POST

[mollcons]

I have just finished building a new PC. This has the following spec:-

Antec Sonata III case

Gigabyte GA-MA790X-DS4 Motherboard

4Gb Corsair RAM DDR2 800Mhz

ASUS Graphics card 2600Pro

AMD Athlon 64X2 6000 CPU

 

DVD drive is an older (fairly new) LG drive

 

Hard drives :

1 x WD 320Gb SATA

2 x WD 500Gb SATA (to be a Raid 1 array)

1 x WD 500Gb SATA - was in my old PC.

 

When I power the box up, nothing happens, apart from all the fans work, and I get the DVD drive to spin up, together with all the disk drives. I do not get any POST beeps, and nothing appears on the screen.

 

I have tried with minimal configuration of board with CPU and still nothing happens. What is likely to be the answer. My gut feel is that the MB could be dead, or I have not plugged something in correctly.

 

Any thoughts will be gratefully received.:confused::mad:

Hi mollcons

 

Does the motherboard have onboard graphics also?

 

If yes, try the onboard graphics.

 

Also try with only one stick of RAM.

The answers to your questions are:

 

No. The MB does not have onboard graphics.

 

I have already tried with both 1 stick and with no sticks of RAM, also I disconnected all drives. Even with just the CPU and 1 stick of RAM I get no sound from the BIOS.

You might be right to think its the motherboard or it could be the graphics card, but i doubt the latter.

 

If everyting is connected properly and in the right place, then i would suggest to try and swap the motherboard out for another one. It should still be under gaurantee.

 

It really could be anyting, but i would swap out the motherboard first.

Thanks Maynardvdm

 

Just one further question before I go to Maplin to get an alternate board.

 

Could this be the CPU? I have not removed the CPU because I would then need to apply new paste which I do not yet have.

[maynardvdm]

Like I said, it really can be anything. It is now a matter of finding which component is causing this. And the only way is to swap out the components one by one.

 

What i would do is when you get the new board ask them to test it there to make sure it is working. You can even take the CPU with and ask them to test it with your CPU in then you'll know if it is the CPU or motherboard. If its neither then you are looking at the PSU or graphics card.

 

Good Luck and let us know how it goes. Any other questions feel free to ask.

Did you plug in the cpu power connector?

Hi Seth

 

Yes. But it is for the CPU cooler, not the CPU itself, which takes its power from the motherboard.

[Seth]

You mean the fan on the cooler?

 

Your mobo has a separate power plug for the processor. Enlarge the mobo image in this link. The connector is to the upper left of the cpu socket:

Found the problem. There is a power socket that sits to the left of the gold colored chip in the middle of the board which was not connected. Also, I had purchased the incorrect ram sticks. I am now waiting for the correct ones to arrive, and hopefully, everything will just work. At least I am now getting the system to post, even if the ram doesn't work.

Yes the socket as Seth has said is to power the CPU - there are some Mobo's that use a molex for SLI/CROSSFIRE and the two are not to be mixed up :eek:
