Format computer?

Has anyone ever formatted their computer?
Go to My Computers, C drive, right click format?
What does it do?
What happened after you formatted it?

if you format your comp I think you are basically putting it back at factory settings. pretty much erases everything

when you say formatt your computer what exactly are you trying to do
formatt erases all data from a drive so it s clean again
if you realy want to clean your hard drive you have two choices
1: was it biught after 2004 and if so it would have a factory backup on it which is usually accessed through F8 or F10 try them all?
this then puts it back to the day it came out of the factory
2: you can set up your pc to boot from cd rom either going into the bios or using the short cut shoen on screen to boot sequence eg: F12
then follow the on screen instructions that guide you through the process of installing a new operating system
windows searches for existing windows
delete these
be carefull not to have other drives { external } on and make sure your default I c:
follow the instructions and you should be ok

2 options factory restore or clean install
ask google and the answer is there
you olny formatt as a last stand if all else fails

To formatt your HDD is pretty much to wipe it clean of everything. Don't do It unless you have backups and you are reinstalling windows etc.

Formating Any Drive : Will result in total deletion of the drive.
WARNING EVERYTHING WILL BE ERASED FROM THAT DRIVE!
