Windows 7: Apache Server Will No Longer Startup & COnnect

I have been using WAMP for a long time and suddenly the Apache server will no longer start up. I then installed XAMPP and had exactly the same problem. That tells me the problem is either in my registry or in my Windows 7 system. I have the required C++ files in the system. The HTTP.exe file is crashing

When I run netstat -o I get 127.0.0.1: 31595 and higher instead of port 80

one error I am getting from apache logs is
"[mpm_winnt:error] [pid 10764:tid 2012] (OS 10022)An invalid argument was supplied. : AH00332: winnt_accept: getsockname error on listening socket, is IPv6 available?"

as well as this from event viewer
