Frequently asked questions
Why does my PC reboot without a blue screen?
Windows may reboot automatically after a crash, or the issue may come from heat, power, or an update.
Can automatic reboot damage my files?
Yes if files are open or the disk is already fragile. Backing up quickly is a good priority.
