Test all leads that attach to your hard drive including electrical extensions,IDE,SATA
the leads from your "((MOTHERBOARD TO THE HARD DRIVE))" make sure they have a secure connection and are not faulty or just replace them they could be faulty make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electrical extensions or just replace them they could be faulty a computer needs its connections to continue its cycle and have an end so any faulty leads will end up with a computer error hope this helps
