Want to secure your computer files more than just the windows password,
BE WARNED IF YOU FORGET YOUR PASSWORD OR SET THESE SETTINGS THE WRONG WAY THE ONLY WAY OUT IS TO WIPE EVERYTHING AND START FRESH.
BE WARNED, backup everything before you do anything more, But please do read on, just do not do anything unless you backup what you have already.
Bios password (does not stop person taking out hard disk and reading files, just starting up computer):
Setup hard disk password and bios password in Bios here a tutorial //www.lockdown.co.uk/?pg=biospsw works quite well but some system have ways around this it does however give you a quick and easy solution to locking down your computer before it even starts up.
Hard disk bios password:
It is a well known fact that most hard disk manufacturers have their own hard disk encryption to secure laptops using the chip that is on the hard disks, this is a recommended option and does not take as long as normal full drive encryption.
1. Restart the laptop
2. Press F10 or F2 or F11 depends on manufacturer along bottom when you startup will be list of options.
3. Go to Security tab
4. Set the password for your hard disk
• Power-On password

Full drive encryption:
PC Free options and highly recommend is True Crypt, //www.truecrypt.org/ works very well and very easy to use, they make sure you backup everything and that you are sure that you want to make any changes, however it is quite important to store your usb key with decryption key elsewhere and make sure you have a Strong password that you will not forget.
Mac use file vault in preferences settings and just start it and thats all, have not much experience with this but have read great reviews on it.
PC Paid version just use Truecrypt it works very well and very happy with it.
True crypt also has a portable USB version for memory sticks and files on the go.
Store everything off your laptop in the cloud and then just use your laptop/desktop as a terminal to your files.
Location security is very important also, no point in having really strong passwords but you store them all on your computer in a text document called password.txt or stuck to your comptuer screen.
