Sorry it took so long Bruce,life intefered.Anyway,I replaced every power connection,that didn't work,then I removed both hard drives and tested both on a friends computer,they both work fine.Windows message still comes up that it's an error in the software,which may be right,message being "load needed DLLs for kernel".I haven't a clue as to what that means.The exact message is "Windows could not start because of an error in the software",followed by the load needed etc.Do you know of a site I could go to to try to fix this?Btw,this really proves the value of back-up,losing every bit of everything can be disastrous.
