oh cool. well guess what the computer is now fixxed..... i took it to a place in town and he pulled it apart and rebuilt it piece by piece. and when her turned it back on he said he couldnt fault it.. he seems to think that the motherboard spacers were different heights and may have ben bending the motherboard and not allowing the ram to sit rite, or some of the usb wiring on the motherboard was on wrong... but he told me plenty of times that he could not pin point any 1 problem that would cause such mischief.. 7 weeks! thanks for the help guys much appreciated

Good stuff
Never even thought of asking about the risers...

Marked as resolved - thanks for keeping us updated
