|If you bought the old computer brand new and you never made any restore disks then you may still be able to do that. |
OEM computers like Dell allow you to make ONE restore set in case your hard drive were to die. In order to just reset to factory condition you can do that without the disks.
You will need to read the manual for your Dell in order to learn how. It usually involves hitting a certain key/s at start up to enter the recovery mode.
I would recommend you try to create the restore disks because sooner or later someone will need them.
Also, be sure you copy all your personal files to CDR or DVDR prior to resetting the drive to factory settings.
Be sure to label any restore disks you create with the description of which computer they go to.
Norton and McAfee are both bloatware. Below is a link to one that many here use.
