PC issues basic fix/troubleshoot

Run SFC (System File Checker)

It checks your system for corrupt system files and will replace them with new known good ones. 

  • Press the Windows logo key, and type in cmd. Right-click Command Prompt and click Run as administrator
  • Type sfc /scannow and press Enter
  • Wait for this process to finish. Then restart your computer
  • You may have to run this up to 3 times to fix all the problems

Then, move on to the DISM check. 

2: Run DISM (Deployment Image Servicing & Management)

  • Windows logo key, and type cmd. Right-click Command Prompt and click Run as administrator
  • In the Command Prompt window, copy and paste the following commands and press Enter, the final command sfc /scannow will not run

Dism /Online /Cleanup-Image /CheckHealth
Dism /Online /Cleanup-Image /ScanHealth
Dism /Online /Cleanup-Image /RestoreHealth
sfc /scannow

Restart your computer when all the checks are done.
If the repair is successful you may want to re-run SFC just to check.
