My laptop is a Toshiba Satellite with an Intel i7-4700MQ, with 8 GB. I am looking at buying a new machine but thought reinstalling windows might help. I have no problem installing updates. But more and more frequently the hard drive pins at 100% and when that occurs all the apps are dysfunctional, usually stating that the app is not responding, even Task Manager. I have backed up all my files to a portable hard drive. What I am concerned about is having to reload all the apps, and more so all the updates this laptop has received over the years. Originally purchased new in 2013 with windows 8. Are there plain instructions on how to do this?
