Use the native program check disk. The first part shows how to do it from a cmd promt. Below that is a section that shows how to do check disk by right clicking on C drive, properties, tool with no command line needed. I copied that part from NeoSmart
Press the windows key on your keyboard.
Right click cmd in the list and choose run as administrator
If it's the C drive use the following.
If it's a diffrent drive letter replace the Capital C with your drive letter.
chkdsk C: /x /f /r
If it's the system drive you will be asked to run it on next reboot. Type Y if you choose to do so and reboot.
/x forces the drive to dismount so check disk can run if it's not the system drive that your booted up on.
/f fixes any errors
/r finds bad sectors and recovers any readable data on those sectors.
If you want to see all the option type
To run the check disk utility from Computer (My Computer), follow these steps:
Boot into Windows 10
Double-click on Computer (My Computer) to open it.
Select the drive you want to run a check on, e.g. C:\
Right-click on the drive
Go to the Tools tab
Select Check, at the Error checking section
Click Scan drive to begin the scan:
If you receive the following message, You don't need to scan this drive: 'We haven't found any errors on this drive' You can still scan the drive for errors if you want.
If errors are found, you can decide if you want to fix them. Depending on the results of this scan, the utility will report the results: If no errors were found, you’ll see this message: Your drive was successfully scanned Windows successfully scanned the drive. No errors were found.If errors were found, you’ll see this message instead: Restart your computer to repair file system. You can restart right away or schedule the error fixing on next restart
If chkdsk dosen't work it sounds like a software issue then. Open a command prompt asks run sfc /scannow and see if that helps. If not you could have corruption, virus, malware, or the left overs of a bad registry cleaner if you ran one. If you've loaded any free software they come loaded with stuff you don't want sometimes. If sfc doesn't work you may want to try the HijackThis forum. Those guys are amazing at finding malware and viruses.
the result of that scan was: Windows Resource Protection found corrupt files but was unable to fix some of them. Details are included in the CBS.Log windir\Logs\CBS\CBS.log. So what can I see in that log that is relevant? – GwenKillerby 25 mins ago
That log may show what file is corrupt. If it does you may be able to replace the file with a good copy from a good running computer or installation disk.
You may need to do a Win 10 refresh but try this first.
Open an elevated command prompt (click start, type cmd, right click cmd and choose run as administrator).
Dism /Online /Cleanup-Image /RestoreHealth this will take some time.
