sorry ermm newbie on the not posting without ram!
Well seems the problem is that power and reset switch have a problem.
With power switch and reset switch correctly place of the f panel pins(as stated by manual) when the power button was pressed all fans and lights came on but no post beep. then if i held the reset button down the cpu fan sped up and it posted.
no ive removed reset switch and all seems fine at the moment.
Its very bizzare to me why that would happen!
Oh and the ram has been detected as 1333Mhz instead of 1600Mhz.
