IMO you're looking at a dying hard drive (based on the tests that you ran in Post 8 and 11) - if that is the case, then backing up your data is now a priority!
First, I'd run a bootable diagnostic that'll be free from the website of the manufacturer of your hard drive to see if the disk is truly dying.
You may want to then try a low level reformat of your hard drive, followed by partitioning it and formatting of the drive - this "may" recover the drive (but will definitely destroy anything on it - to include the recovery partition). Make sure you've got the Dell recovery disks before doing this!
Once this is done, run the bootable diagnostic again to see if the above procedure has fixed things (I doubt that it will, but it's worth a shot!).
Either way, you'll be starting over with a blank hard drive (either a new one, or the one you've run all these tests on) - so you'll have to restore the OS with the Dell Recovery disks
BTW - I just repaired a Dell laptop hard drive by installing the one that the customer ordered from Dell. It came with everything installed already and just required setup. I've been unable to locate any info on the Dell site, but it might be worth a call to ensure that the drive that you order will have the image on it.
