My microphone wont work?

Question

Hello, my microphone recently worked before my dad reformatted the computer. At the back of my PC it has 3 holes, pink , green and blue. I have 5 speakers and a sub , (surround sound) and when i plug the three cords connected to speakers it works, but when i unplug them and put my microphone things (one green end for sound and one pink end for talking) it wont let me talk, it will only let me hear through the headphones, (I attached pictures to end of this for more help)

Please email me at [e-mail] or just respond here

Answer 1

your keyboard is so dirty

Answer 2

Try

Start->Settings->Control Panel-> Sounds And Audio Devices

Under the Audio tab, make sure there's a device listed for Sound Recording. Hit the Volume button in that section, make sure the mike volume is at least 50%, but most importantly, that the "select" box is checked.
