Issue: How to fix "The computer restarted unexpectedly" error in Windows 10?

I tried installing Windows 10 on one my laptop. When the PC loads, “The computer restarted unexpectedly” message pops up and it freezes while loading. The error appears each time when I restart the system. I’m out of options. Where might the problem possibly be? Thanks in advance.

The computer restarted unexpectedly” error occurs not only in Windows 10 but also in previous versions Windows 7, 8, etc. Each case is individual, so there are many theories about the cause of this error. Interrupted power supply might have triggered the phenomenon. Otherwise, it is likely that if attempted to install the Windows iso file, which was downloaded from questionable sources, the corrupted files might prevent you from upgrading to Windows 10. However, there is a simple solution to this problem. Take a look at the below instructions. If this method helps you successfully install the new edition, make sure your system is protected from all sorts of virtual threats. In that case, install Reimage.
