Putting it simply, after I ran Windows Update I soon started to experience endless critical_process_died blue screens. I'm unable go for any longer then five minutes after logging in before I get if again. Additionally, I attempted to run chkdsk as part of my diagnosis and inadvertently found myself with chkdsk looping because it can't finish. When it tries to run, I just get a critical_process_died again and the process repeats. There is no ten second message for chkdsk.
