Connect 7.1 speakers to my computer

[markfirst]

How can I connect Creative 7.1 speakers to my new computer which has standard audio ports (green blue and pink)? The speakers have 4 cables (Orange, black, grey and green)

You're going to need a amp which will be connected to your computer and speakers, I would help more, but i'm not a expert at these stuff.
