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.
