Would like to know how to Completely Lock-down Windows 7 OS

Question

I don't have a general question..
It's more like specifics about how to lock down windows 7 computers..
Here's a little background information...
I have two computers, both with win 7(Pro, and home prem).
A family member can somehow bypass all bios and all windows security services... Everytime I go to work or school, he will power on my desktop and somehow 'hack' into the OS and install keyloggers or viruses so he can obtain my banking or other personal information.
He also unlocks and deletes all the passwords so he can have access whenever he wants..
Can someone please tell me how to do a complete lockdown? This is getting extremely annoying.. I've done everything that I can do; Also considering on switching my major to some sort of computer security. I'm starting to lose my mind over these months.. All
help is appreciated.
I've password protected BIOS
I've disabled administrator accounts, i've put password on the admin and the guest user; locked the option to change passwords..
All help is appreciated. Thank you all in advance.

Hi,
If you are using Windows 7 Professional, Ultimate, or Enterprise, you can use the Local Group Policy Editor to change policies that affect the security of your computer. Please check if the following policies meet you requirements.
[User Configuration\Administrative Templates\Windows Components\Windows Explorer]
Enable these two polices:
Prevent access to drives from My Computer
Hide these specified drives in My Computer
For your reference:

Also, restrict Which Programs a User Can Run. You can set rules in AppLocker in the Group Policy Editor that prevents all programs from being run.
In addition, temporarily Lock Your Computer if Someone Tries to Guess Your Password
If you share your computer with other family members or allow your friends to use it, you should have a password on your Windows account so no one else can log into it. However, someone may try to guess your password and log into your account. If this happens,
you can temporarily lock your computer.
You should also periodically change your password.
If you suspect, you family member using a tool to bypass your password. You may use Malicious Software Removal Tool (http://www.microsoft.com/security/pc-security/malware-removal.aspx)
to remove it.
Hope it helps.
