Your PC run in to a problem do not shout down it until

The operating system is corrupted. The best thing to do is to reinstall a fresh copy of Windows.

1. To recover data: You need to extract the SSD or HDD and use a SATA to USB connector and then go to your disk --> select Users folder --> Get your username that you usually see on the Windows login screen --> Grant permissions --> Extract whatever you need.
2. Once you've extracted whatever information, you need to format the disk in "Create and Format hard disk partitions". Once you've done that, put the SSD or HDD back in.
3. Reinstall a fresh copy of Windows: You need a USB at least 8 GB to install Windows Media Creation Tool, you can get it on the official Microsoft page. Format the USB to FAT32 (This will delete all the files within the USB) and run the .exe program of the Windows Media Creation Tool to make it bootable.
4. Now Insert the USB key into the USB port and then once it boots to the USB select the 64 bit variant and follow the instructions.
