Hi,

It could be that your hard drive is starting to fail. Use some programs to run some diagnostics and start backing up you personal files. If it is bad you will need to replace it. Programs for diagnostics:

 

Crystal disk info

HD tune:

Use these to see health of drive.

 

Let me know if you need further help,

David
