I would try reseating everything to start to see if it is a bad  or dirty connection.

power is getting to the MB because it has lights plus the front panel has lights, i am guessing it is a fault with the MB, just wondered if anyone knows what the flashing lights mean ?

The following is every led for the G3 I beleive that they were close to the same. On the Hp site it goes through each led by where it is on the board and tells you how to troubleshoot for each light.

... i do have power lights on the front panel....
If it is green this indicates your power supply is OK. If the power button show amber color, could be fail power supply, memory, or motherboard

....when booting the LED's on MB CR2,4,7 and 10 come on, CR 13, 14 flash alternatley
Unless they are red or ember color to tell you the part is failed, all flashing green LEDs are OK (just indicated you have activity going on)

Suggestion:
You may want to bring the server down, unplug and hit the power button to drain all the power. You then take out some memory dimm and reseat the remaining dimm. Try to boot it up with small number of memory and swapping your memory to detect a bad dimm. If you have spare dimm, replace with spare only.

Does anyone have any idea, i get no Red or Amber lights on the system board which would indicate no failures, just flashing green which would indicate activity.
I have drained power removed all memory removed bios batt, still getting no POST. ?

I have drained power removed all memory....

HP server will not boot if there is no memory installed. I have seen a server with your situation and it boots fine after installed new dimm. Do you have a spare dimm? Call HP if you still have warranty on it. They will replace failed component for you even your MB.

If no dimm is installed i was under the impression that a series of beeps are given ? however i dont get this, which leads me to think it's not the DIMM

It's true, but what if your speaker is jacked off?
Anyway, contact HP to replace components because the problem could be your motherboard and if you have service warranty they will come in to replace it for free. It's just solely hardware problem and what you can do besides swapping parts is running hardware offline diagnostic:
