Windows 7: Realtek Drivers Uninstall automatically.

Hi, I have a problem. My Realtek sound drivers keep on uninstalling themselves. I will install the drivers and I will then reboot as I says too, I reboot and they are there, if I boot the computer down and boot it back up the same day they are fine, no problems. But the next day when I go to boot up the pc I have no sound what so ever, I noticed that I have a HDMI Audio Driver, I disabled this and the problem went away for a few days.

I did a complete re-install of Windows 7 and I still get the same problem, I would like some help, i've tried a few different things, i'm going to install the drivers now and re-boot.



Thanks in Advance (By the way, I have googled every time to find a fix and hardly any were permenant!)

Do you have an HDMI cable connected to the PC? In most systems, if there is an HDMI cable connected Windows will automatically set the HDMI as the default playback device.
