If you use Windows on a daily basis, you might encounter an experience where the system automatically restarts itself.

Normally, Windows can fix some blue screen of death (BSOD) errors by restarting your computer. However, your computer may randomly restart without any error message. This is an annoying problem because it can happen at any time. For instance, during activities like gaming or video watching, the most disruptive situation occurs when the computer unexpectedly restarts, resulting in the loss of all data and progress.

You might be wondering: Why my PC restarts automatically again and again? And how to recover files lost after a computer restart?

Generally, computer rebooting randomly can be caused by many reasons, for example, the misconfigured automatic restart feature, overheating or a faulty power supply, a faulty RAM, virus or malware infection, driver problems, a Windows update, etc.

Next, we will show you how to recover deleted files after a computer restart as well as how to fix the issue of “PC randomly turns off”.

Recover Files Lost After Computer Restart

It is very common that files are missing after a computer restart in Windows 10/11. If you encounter such a situation, how should you proceed to recover the lost data?

When you find a file missing, you can go to File Explorer, type the name of the lost file in the search bar, and hit Enter to verify its presence. If not, you can use a piece of professional and free data recovery software to restore files lost after a computer restart.

You should stop performing any operation on your computer when the PC restarts automatically or randomly and deletes files. Or else, data overwriting is likely to occur. As a result, overwritten data will be unrecoverable.

If you are not sure which partition the lost data is in or the files in many partitions are lost, you can move on to the Devices tab and select to scan the entire disk.

More importantly, to check whether the listed files are the wanted ones, you are allowed to preview them. Multiple types of files are supported to preview, such as videos (MKV, WEBM, MTS, 3GP, MP4, etc.), pictures (JPEG, JPG, JPE, BMP, etc.), documents (DOC, DOCX, etc.), audio, and more.

preview the video

For video/audio files and most pictures, you can click the “Save” button in the preview window to save them one by one, or you can select the checkbox next to each desired file and click the “Save” button in the scan result window to restore the wanted files at once.

save wanted files

After clicking the Save button, you need to choose a storage path to save the required files. It is recommended not to save files to their original location to avoid overwriting deleted data.

MiniTool Power Data Recovery Free is effective in scanning, showing, and previewing unlimited files, and supports 1 GB of free file recovery. To break this data recovery limitation, you need to choose an advanced edition like MiniTool Power Data Recovery Personal Ultimate.
