^^ steps to "defragment" a hard drive:
open MY COMPUTER > right click first hard drive, (usually C) PROPERTIES > and out of tabs called GENERAL, TOOLS, HARDWARE, select TOOLS . defragmentation is usually second group (after ERROR CHECKING) . click DEFRAGMENT NOW.
disclaimer: i have a feeling, this is not it, leave the computer however overnight for properly doing it. use settings/options called AUTOFIX errors before you start defragging
ok thanks alot :)
