You can delete the old OS and expand the new one into the space. Post back a screenshot of Disk Management - Post a Screen Capture Image and we will give you the steps.
Okay, here is a screenshot of the Disk Management page.
Just backing up a little re the sound I see you have Asus Xonar speakers and for the cost of the card why not swap out the THX TruStudio one for an Asus Xonar DG?? I have them in all my desktops and never a problem.
Depending on where you live of course the cost of these are minimal and the GUI for mixing and effects are something else. (I paid $35 for my cards) https://www.asus.com/au/Sound_Cards/Xonar_DG/
Plus I drive 5:1 Logitec Z506 systems from mine and couldn't be happier.
