Hi there, could you try the following steps please? Specifically, to check your hard drive for errors: All storage drives/devices can be affected by file corruption, especially if it is older or running under a heavy load. You'll want to work with a specialist to investigate possible issues with your Hard Drive.
For Windows: My PC → Right Click on Drive → Properties → Tools → Error checking
