My mom gave me her old laptop cause she got a new one. I want to play minecraft on it but it is really laggy cause she probably cluttered it up with a lot of stuff. I want to revamp the laptop so it would run like new again. How would I do that?
Reinstall Microsoft Windows. You'll need the original discs with the serial number. During the installation process it will ask you if you want to "format the hard drive" ... say "Yes" (this will completely remove all programs and files).
Note: be sure to backup anything on the computer that your mom might want. You can upload files to an online storage system like dropbox.com for backup.
Also be aware that doing this will completely reset all settings. It may require you to setup your internet connection again, so find out your username/password.
*** Instead erasing the computer what about going back to a previous date; such as when your mom first gotten the computer in that way you do not need the start up disk:
Windows Vista and 7 users
2.In the Start search box type System Restore and press enter.
Windows XP users
2.Click Programs, and then Accessories
3.Click System Tools and open System Restore
If you're unable to find System Restore and have administrator rights try opening the System restore through the run line by following the below steps.
