What tools are you using to format drives ?
Did you try the boot option "Test this media and install Fedora " when you boot from DVD ?
If no os is installing on the hard-disk your hard-disk may be corrupted .
Try Hiren's boot cd , It has got many tools to test hard-disk and also rescue options .
You can get it from here
