How can i completely reformat my computer?
if you want to reformat and delete everything so your comp. runs as smooth as possible, then your gonna lose your iTunes. Its simple put in the OS for vista and turn of the computer and turn it back on it should tell you somewhere on the black screen to boot from CD it should be like F8 or F10 w/e. press it then it will go into a blue screen do some loading then it should come up with a OS installed , delete it and install a new one should tell you the buttons to press. takes about 3-5 hrs to do a fresh install of an OS unless its Windows 7 it was fast like 45 mins.
