Looping sound hard lock on login screen

Today a little problem cropped up as I tried to watch a youtube video. As soon as I go to open it I got a sound loop crash (sounded like buzzing) and when I went to login it would crash on the windows 7 'jingle' at the login screen. This started happening the restart after I did a windows update, specifically KB982018, KB2532531, KB2529073, KB2675157 and KB2505438. I also used a TCP optimizer and ran this batch file to further optimize my internet connection beforehand:

I have since reverted the changes made by the TCP optimizer and that batch file by manually changing the settings back on the optimizer and using the built in reverter in the batch file, with no change for the better. I'll try uninstalling the windows updates one by one now. Any help is appreciated and thanks in advance.

Hello Craftyman, to Windows 7 Forums,

It may be a little quicker and to be sure all remnants of the batch file and those recent updates are gone, to do a "System Restore"

Hope this helps
Don
