Hi,

I recently purchased the following

Intel Core 2 Duo E6750 "LGA775 Conroe" 2.66GHz (1333FSB) - Retail

Asus P5K Intel P35 (Socket 775) PCI-Express DDR2 Motherboard

GeIL 2GB (2x1GB) PC2-6400C4 800MHz Ultra Low Latency DDR2 Dual Channel
Kit (GX22GB6400UDC)

Sapphire ATI Radeon X1950 Pro 512MB GDDR3 HDTV/Dual DVI (PCI-Express) - Retail

I've put it all together and and all that happens is the Cpu fan spins up for a second and then shuts down. No bios beeps or anything. I have taken everything apart and rebuilt again outside the chassis but still get the same problem.

Has anyone any idea what the problem might be. Could the RAM be incompatible with this motherboard? Does anyone recognise these symptoms and know what the problem might be i.e. duff Motherboard?

I bought a new 500w power supply also to cope with the graphics card and have tested this with my old kit so i've ruled out that as a problem but as my old kit is all incompatible with the new this is the only part i can swap between the two.
 
Hi, try installing only 1 stick of ram then the other just incase of faulty stick, try resetting the BIOS.
Do you have all the power cables plugged in.

Cheers Rob,

Yep tried different sticks of ram, 1 at a time in different slots. I've also tried reseting the Bios, The two power cables are plugged in the 20 pin and 4 pin. The LED is on, on the motherboard so that is getting powered. With all the different things i've tried all i can get it to do is spin the fans for a second and then switch off.

On the power cables (just to clarify) you have the 24 pin ATX connected and the four pin by the processor.

Could be a short somewhere.

I'd unplug everything, all drives, graphics card, ram etc... then just leave the CPU in the board (cooler too obviously) and gradually introduce them back in to narrow it down.
 
Rob you could be onto something.

My new power supply has as 20 pin connector and a 4 pin connector the motherboard has a 24 pin power socket. I assumed that it was split to be compatible with older ATX boards as my old board has a 20 pin power socket. I've just looked at the manual and yes there is a 4 pin power connector by the chip that i haven't plugged anything into.

Does this mean there should be another 4 pin power connector from my psu or my psu is not compatible. I'm at work so I can't check this out until i get home.
 
That'll be it, I won't boot without the 4 pin in.

The 20 pin will feed a 24 pin socket, it'll only go in one way. The 4 pin is still for the lone 4 pin connector.

What make is your power supply, like you say the ATX power supply from the PSU has a removable 4 pin for older motherboards, new motherboards require this plus another 4 pin (8 pin in higher spec motherboards) which supplies voltage to the CPU, this tends to be yellow and black, thats why you motherboard is powering up and shutting down.

When you get home check your PSU for this extra connector if this does not have this cable then a new power supply is needed.

Rob thanks very much for your help, you're a star.

The PSU is an X-power 500w i've just looked at the specs from the net.
The connectors are as follows

Universal 20 + 4 Pin Main ATX Power Connector X 1

4 Pin + 12V Power Connector X 1

6 Pin Power Connector for PCI Express Graphic Card X 1

Peripheral Connector (4 Pin for HDD, DVD … etc) x 6

Floppy Connector (4 Pin) X 2

Serial ATA Power Connector X 1

24 Pin + 8 Pin adapter for AMD ATXGES X 1

So it looks like it does have it and i missed it. Hopefully this will sort out my problem.
