New system won't boot

[tron2k3]

Hi

I ordered a new system and started to build last night.

The spec as follows:

DFI LanParty UT NF4 SLI-D
Amd Opteron 144
Geil value 2x1gb
Hiper 480w Type-r
Connect 3d Ati rad 1800xt 256mb
Matrox sata 250gb 16mb cache

I've plugged all 4 power connectors onto the board.

The problem is it doesnt boot, it won't even go to the bios screen.

It powers up with the lights on and the 4 leds light up on the board and stay on, I've tried clearing the cmos with no luck. I've tried different ram and it does the same and the gcard powers up fine.

I think its either a faulty mboard or cpu, or maybe the power supply isnt upto the job, or am I missing something obvious.

TIA

Will

Make sure you have the plugs for the switches/LED's in ther right place. It's easy to misplace the plug for the power switch and thus not be able to turn the system on.

What ram slots do you have the ram in. Stupid question I know but having had the problem myself and reading up on it the DFI boards (NF4 based ones) can be really picky about ram (depending on the bios).

I think the yellow slots are higher voltage preferably whereas the orange slots are for the lower voltage type ram.

(mine for example hates being in the yellow slots).

May be worth a shot.

my guess as well in the first instance
the motherboard headers-are the switches and lights wired up properly

He does state that the system boots and then comes up with 4 leds (which I cannot remember what that stands for in the DFI manual).

LED's come on on a motherboard with power applied but the mobo effectivly off.

Agreed if it is indeed the power led's however the DFI also has the debug leds (4 of them) which turn on then off in order. (with each step in the order meaning a certain issue)

Thanks for the replys, I've used slots one and two for the ram which are yellow and orange I believe and also tried a single ram stick in slot one.

The led's I'm referering to are the ones are the board and the manual says 4 lit up means power and should go off but it doesnt.

Can you try a different PSU?

my old psu is a 350w, not sure if that will cope, i will try and get hold of another.
