Frozen

Pheeew, exciting times. Three days ago my laptop began to freeze continuously. I managed to reboot it one more time, copied all the latest files for my book onto a thumb drive and, five minutes later, the machine was as unresponsive as a brick wall.
With lots of coaxing I was finally able to reboot it in recovery mode and reformat the entire thing.
Now it’s all good. Adrenaline levels are back to normal and backups are transferred to the “all new” machine.
Has anything like this ever happened to you? I am still sweating and have been reminded once more to not trust my gadgets too blindly and to back up religiously!
