No playback devices

Hi, this is my first post on a forum so this is probably all sorts of wrong.

The other day windows updated some keyboard drivers or something before i turned off and removed my graphics card to try sort out the heat sink. Anyway, since then my pc has been unable to detect any of the audio ports attached to the motherboard. I've tried various suggestions on other threads but none have worked hence my first post.I understand for any help ill likely need to give more information and ill happily provide such details.

So yeah, help. Plaese   Thanks
