Okay, I check the box of Shaders in the options menu then clicks the OK button. Then it lags for a bit then nothing happened. When I go back to the Options menu, the Shaders button is unchecked. What do I do to fix it?

Your video card is not updated.

Please show the specs of your video card so that we may get the right update for you.

How do i know the specs? I'm a noob when it comes to computer.

Don't you have the receipt or something? Some paperwork?

Ummm....no. Our computer's old.

You will probably need a totally new one then.

Awww man. I thought you need to download something. Thanks anyway.

Don't listen to me though, I know nothing about computers.
