Sure, happens all the time. That's why I quit fooling with Mickey Mouse.. But, aside from that, take a look at your last update from MM. Uninstall those one at a time, and reboot between each. Also, do NOT, use automatic updates. I think you know why Once you get your PC at a decent working level, do your updates, MANUALLY, ONE AT A TIME. Test in between to make sure nothing else is broke. Good luck!! Zeek
