Hey guys,

This morning, after booting the computer, I entered BIOS setting program. But it struck me a lot. I can not enter all the settings except these three items: User Password, Save Changes and Exit, and Exit Without Saving. I do not know why this happened. The operaitng system on it is Windows 8 home premium. And the last boot of the computer was by my friend.

Can you give me some suggestions!

Thanks a lot!
