Ok, this is really starting to annoy me now...Yesterday my pc started to behave very odly out of the blue, I kept getting the blue screen of death and stop errors (Unkown hard error) I began to run scandisk which took quite some time but did finally complete. I thought this had cured it until I got the stop error again. I restarted the pc and now I am getting a boot disk failure! The HD (Sata) is not being detected in the bios (I have checked the connection and even plugged it into a different sata socket) I can hear the harddrive trying to spin (Its not making the deadly clicking noise) I am assuming it could be a corrupt MBR? Problem is I cant fix anything as the harddrive isnt detected at all! Any ideas? Ive thought about putting an old IDE Hd with windows on and seeing if somehow I can access the sata hd from within windows although I think this is unlikely if its not detected in the Bios. Any ideas!? Thanks, Dave
