I just ran System Information (under System Tools in the Start Menu) and interestingly it lists Realtek and that it has been installed, see below. Seems the Realtek is recognised by Win7?
I had done what you suggested to discharge internal capacitors after I installed the replacement mainboard. I will try that again just in case and report back.
Thanks.
