If your hard drive is not recognized, that may indicate that it has failed. My suggestion would be to try booting to your Dell drivers and utilities disc. Insert the disc, then tap the F12 key when you boot and select the option to boot from the DVD drive. If you are not able to boot to the DVD drive, go to downloads and grab the Dell diagnostic package that can be used to create a bootable USB flash drive. Try booting to that and run the diagnostics from there.
