Jack being detected with nothing connected. Help please

Hello, i am having issues with the sound on my pc, i've been using it for months, but never had this problem before, it detects something in my green front jack, but there is nothing connected there, and it doesnt seem to detect when i connect into the rear panel jacks, i even tried unplugging the front panel from my motherboard, it still wants to detect something there :S
My pc info

The problem

My settings

i have, also tried reinstalling them from scratch, tried both hd drivers and ac97 drivers etc..

That really is weird. Ok try to reinstall the software from your sound card, before you do that get the new drivers. Unplug all jacks beforehand. Then see what happens.

what software? im using an inbuilt realtek card
