Okay... here it is. This is a patch that has been known to fix the alarm issue. It's does not work for everyone, which is the reason we are now giving it out. We have had a very good ratio of cases where this has fixed the alarm issue but we had a few cases where it wouldn't solve the issue. We suspected hardware issues in those cases where it hasn't worked, but we have given up trying to fix Microsoft's problem. I really hope you all can get some use out of this as we spent many hours on it!
Please make a backup before using, especially for level 3 of the fix.
