how can i configuration my hard drive to set to the factory default because my acer aspire 5336 disc are not letting me do it ?
When you say "configuration my hard drive to set to the factory default," do you mean that you want to restore your computer to the state it was in when you bought it? If so, the only way to do that would be to reinstall Windows 7. You put in your Windows Disc, which should have been included with the machine, boot from it, in the drive selection, go to advanced and reformat the hard drive, then finish installation. It's a very streamlined and straightforward process, I don't think you'll have much trouble figuring it out.
