Last check before RMA. No POST no Beeps.

Hi, I recently bought the following

Intel Core 2 Duo E6420 "LGA775 Conroe" 2.13GHz (1066FSB) - Retail
Gigabyte GA_P35C_DS3R (Socket 775) PCI-Express DDR2 & DDR3 Motherboard
Crucial Ballistix 2GB (2x1GB) DDR2 PC2-5300C3 667MHz Dual Channel Kit

I put all this in an Antec Sonata II Piano Black Quiet Case - 450W Smart Power PSU with a X1900XT from my current machine.

When I power it on it does not post and does not beep and no video signal but all the fans (GC + CPU) startup and a light on the GC comes on. I have tried/checked the following.

Cleared CMOS both by removing battery for 30 mins and jumper. Both with PSU unplugged.
Tried booting with only CPU+HSF, mobo and PSU
Tried booting with only mobo + PSU
Reseated CPU + HSF several times
Tried building outside the case to eliminate shorts etc

I have checked that both the 4pin 12v ATX, 24pin ATX connectors and the PC speaker are all attached. The PSU runs my current system fine (3700+SD, 1 DVDRW, 2xHD, firewire, many usb attachements).

Am I right in thinking that even without a CPU the mobo should still beep? IF this is the case then the above tests narrow faulty compents to mobo or PSU and given that PSU works on my current system I am assuming that the mobo is the culprit.

Is it time to RMA or is there anything else I can try?

Haven't tried any other ram but have tried one stick at a time. Wouldn't I still get beeps though if it was dodgy ram?

Its interesting because in the Motherboard forums there is this thread HERE which in the first post states that the most common problem is a duff board or ram and then in the Booting issues section mentions fast C2Ds. Surely though if it was ram or cpu there would be beeps when powering on and these compents are missing.

yes tried it all again outside the case.

There is another point - I left the fans spinning for about 10 minutes before turning it off then quickly took off the HSF. The cpu was not hot at all.

Gonzo0, Did your motherboard beep when you tried booting without the CPU?

I don't have access to any other ram.
Anyway if I try booting without any ram in at all there are no beeps (it should beep during post to let you know there is no ram)
