It started after some updates from Microsoft. I uninstalled the updates then reinstalled them one at a time. Nothing changed. After several weeks of uninstalling drivers updates and and anything else I could think of then reinstalling same I finally told it to recover the system back to factory specs. Still the same. The mouse acts like it's drunk, software and web pages hang and freeze and I get a message asking me if I want to change my color scheme. Could something be going bad in my laptop?
