100% cpu usage.. Computer runs like a slideshow.. I wrote down the time, and it took 15 minutes to login to windows and it is impossible to ctrl-alt-del or do anything.. Our Windows 2008 Server running 4.0.417 deadlocked during operation like this... Then it would fail over to a server with 4.0.314 and it would do the same thing.. I had a good friend this happend to running Vista at home.. He came home and it was a slide show.. I reverted back to 3.0.672 and now over a week no problems.. The only thing I can find with an error during this start up in the Event Viewer is the following These problems have only occurred with 4.0 and each release.. I hope this log file can shine some behavior on what is going on in the background when this happens. I have attached Application and System Event Viewer logs.. I am running 4.0.424.0 right now and it happened again.. Same thing as my friend reported on his home machine, same thing on 2k8 server.. I let it hang for 15-20 minutes as you can see in the logs.. Scroll to bottom and read up..
