Right progress report,before putting the machine back together tried the hard disk one last time,this time no bleeps and managed to get into bios,came out of bios and hit F8 to try safe mode,booted to safe mode,yippee!!did system restore,success!!the Draper home made super puter is all fettled
PS what started all this chaos was summat one has done hundreds of times,there's a couple of USB sockets on the front panel,I unplugged the webcam from one and plugged in a memory stick,everything went downhill from there.
Thanks again chaps,never say die.
