yes its a new build 
New motherboard and ram old HDD with recovered repair install XP Pro, so I retained all my programs & data and all now tested  &  running ok. 
6Gb ram all now functional thanks to your help in diagnosing the bent pins. 
No noise thanks to the issue here on this forum diagnosing cure. 
I just want to make sure I have everything correct and running at its best prior to trying to overclock which is something I have not ever attempted.
