Blue screen of death. Computer can't restart. It is trying a restore to an earlier date now.
I rebooted earlier today after checking to see if I needed to do updates. I didn't.
I'm rather upset.
A few months ago I spent days looking for a ThinkPad that fits my needs and the closest I got was 2x the price of this one with fewer features and the same amount of memory and hard disk space.
So I had new memory put into this one.
The problem I had mostly disappeared. Until tonight when something worse happened.
Edited to add:
Got ready for bed because I will be up at 4:30. Checked my computer when ready and found it had finished the restore and wanted peripherals disconnected and shut down. It rebooted to the windows sign in so I will take that as a hopeful sign.
Tomorrow I'll backup fully and get back to shopping for a new computer. Last full backup was 3 months ago. Email backup is the only major missing backup.
