No post, no beeps, no video

Hello,

I have tried to upgrade my computer and have got the following
2x 1GB Kingston RAM
Gigabyte EG41M-S2H Motherboard
Intel Core 2 Duo Processor E6400
430W power supply

I have tried it with another power supply, another motherboard and another processor (E8400) all with the same result.

With no RAM in the motherboard it beeps as it should. The HDD is spinning (I have tried 2 HDD as well). The LEDs on the motherboard are lit, the CPU fan is spinning. I have reset the CMOS. I have taken the entire thing out of the case because I thought the motherboard might be shorting on the case. I have tried only 1GB RAM at a time and there is no change.

Have I missed something??

Thanks in advance.
