One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect your hard drive
Test all leads that attach to your hard drive including electrical extensions,IDE,SATA
the leads from your ((motherboard to your hard drive)) make sure they have secure dust free connections and are not faulty or just replace them they might be faulty
if its a 40 pin flat ribbon type it will be the first to fail
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 electical extensions
even something as small as an electrical fan and its lead can cause you problems
computers need all electrical power and data to continue through every working device and to have an end so any faulty leads will end up with a computer error
make sure your graphics card is securely seated with no dust built up or in the socket
if you remove your graphics check the socket to make sure its dust free
restart your computer then reinstall it this should activate found new hardware wizard
hope this helps you
