Hi guys, I need some help here. I've built a new system and for the past two weeks I cannot get the thing to powerup.

The entire thread can be located here as I've tried to narrow down the source of the problem.

But you don't have to read that if you don't want to as I have summarised my findings below:

Well after a lot of various combinations I have found out the following:

1. The Mobo works fine if it just sits unsecurely on top of the risers

2. As soon as you screw the mobo to the risers it will not power up or it will power up repeatedly and turn or every 2-3 seconds

Has anyone else had the problems that I am having with my GIGA P35-DS4? I have removed all my HDD's etc in an attempt to find the source of the problem.

Spec:
Intel Core 2 Duo 6600
2 x 1 GB Crucial Ballastic DDR2 8500
OCZ 600W ATX2 PSU
GIGA P35-DS4
 
cheers ;)

Well I've actually just had a bit of success. I tried various screws which came with the board and have found some that work....excellent

Now here's the bad news - when I boot the system up I'm getting no video output. I know my graphics card works as I tested it.

What are the chances that I have blown up my processor? I'm seriously concerned about this as I think my processor is dead from all the messing about.

Boot the computer with one stick of memory, if it works, increase the ram volts by + .4

Hi Servo - can you tell me how I can do this? When I power up my PC I get no display out of my graphics card meaning that I cannot even see the BIOS
 
The DS4 should have no issues booting with the Ballistix at the 1.8v default vdimm.

Which cooler are you using? If it has a backplate then it's quite possible that it's screwed on too tightly and is shorting the board when you screw the board to the case.
 
If the problem with the computer, is the memory voltage, then you will get no display to your monitor. By booting with one stick, this sometimes allows the machine to boot, and allow the changing of bios settings.

Once in the bios up the dram volts, save and exit. replace the second stick.

I've had the same problem as you.

Look up the definition of 'should'.

I've had 4 pairs of Ballistix in my DS3P (which, other than the cooling, is the exact same as the DS4) and had no issues at all when booting two sticks at 1.8v). Hence I offered an alternative opinion.

LOl, keep your hair on m8, I know what "should" means.
 
Thanks for your help guys. I've tried to boot it up with 1 stick but still no luck :(

The PC just keeps on booting then shutting down every 2-3 seconds
 
I would if I had any :(

The OP has been able to boot the machine fine when the motherboard isn't screwed down, which hopefully suggests a short somewhere. Tho my initial theory of an over-tight heatsink backplate causing the short may not be applicable as he seems to be using an Arctic Cooler and AFAIK it doesn't use a backplate.
 
Guys - here is something to think about:

Sometimes everything stays on for days etc. Even when this is so I still get nothing on the screen. I honestly think that my CPU is shafted.

Is there anything that I can do which can tell me if my CPU is ok?
 
when the mobo isn't screwed down the board will run for days without any hicups but still I get no output to my monitor. I have checked the graphics card (X1900XT) and everything else as far as I can tell works fine.

The only thing that I havn't tested is the CPU.

I don't know how significant this is but my Arctic Freezer wont even work now. It used when I was building my PC but the fan just won't spin when my PC powers up. I've removed the Arctic just to a look underneath and I can see the paste has spread onto the CPU.

If my CPU had burnt out how would I know?

And the board has a fan controller that starts and stops the fan as it's needed. If the CPU is cool then the fan will stay off til it starts to heat up.
 
I'm just trying to identify the problem. I have tested everything apart from the CPU hence my question.

There maybe a problem with the mobo, I don't know. The mobo does post so I guess it must be working ok?
 
I'm with Cob on this one.
1) I'm sure it's not the cpu
2) Try using the paper washers (red ones) when fitting the motherboard
3) Check your gpu, are you using the 6 pin connector direct from the psu, or the adapter, make sure both 4 pin connectors are used.
4) check the standoff, make sure none are in locations that are not required. (shorting on the m/b)
