What do you need help with, Realtek (sound) or SD card (removable media)
For the SD card go to
Card Reader Driver 5.1.2600.2011.zip - Free software downloads and software reviews - CNET Download.com
Download the driver to your desktop
Go to device manager and uninstall the driver that is there
Reinstall the driver, When it asks if you would like to go on line or browse your computer say browse. Go to the file you downloaded from the download I sent you to.
For a Realtek problem go to the Realtek driver site (link on top of sound threads) and do the same thing
If I have helped click the scales symbol and tell me

Go to device manager (start, type Device Manager) expand (+) the SD entry right click and driver is there

I don't know why you don't have an entry for SD card. Is it in non plug and play?
Click on the + and see if anything is there.

Just a thought, Open device manager and then plug in the device and see if a new entry is opened in device manager. It will close and then reopen.
If a new entry is there that is the driver you need to uninstall and reinstall.

I have multiple places on the front of my tower for digital camera cards, USB ports etc. They all worked at one point but for some reason none are working right now. I tried to download the thing you mentioned but that did not work either. Also when in device manager I am ot 100% sure where the driver is I am looking for.

Still not quite sure what the problem is as you mention Realtek in your heading which is sound, then you say SD card not reading and you also mention USB ports.
To update the USB port driver go to Device manager,Universal Serial Bus Controllers, click the + then go to USB Mass Storage Device, Right click and update the driver from this file
