Hi,
- Did you make any changes to the computer prior to this issue?
Let us follow these methods:
Method 1.
Let us perform sfc scan and check the status.
1. Press Windows key + Q to get the search everywhere option.
2. Type cmd, right click on command prompt and select “run as administrator”.
3. In the command prompt type the following command:
sfc/scannow and press enter.
4. After the scan, restart the computer. Once this is done run defrag and check the status.
Method 2.
One of the best ways you can improve your PC's performance is by optimizing the drive. Windows includes features to help optimize the different types of drives that PCs use today. No matter which type of drive your PC uses, Windows
automatically chooses the optimization that's right for your drive.
Be default, Optimize Drives, previously called Disk Defragmenter, runs automatically on a weekly schedule. But you can also optimize drives on your PC manually.
Refer to the section “To repair a drive” from this article. Once the check disk is done, restart the computer, run defrag and check the status.

Important: While performing check disk on the hard drive, if any bad sectors are found, then check disk will try to repair that sector. Any data available on a bad sector might be lost.
