Hi ShannonMarie,
a. Did you make any prior changes to the computer (like installing any programs or updates) before the issue surfaced?
For now, I’d recommend you to open event viewer and check if there are any significant details related to the issue.
Refer the following Microsoft article for more information on event viewer:
What information appears in event logs (Event Viewer)?
http://windows.microsoft.com/en-US/windows7/What-information-appears-in-event-logs-Event-Viewer
Let’s check the drive for any errors and check if that fixes the error.
You can also run check disk from command line instructions. Refer the following TechNet articles for more information:
Chkdsk

Note: If any bad sectors are found while running the check disk utility and if attempt recovery of bad sectors is checked while checking the drive for errors, the data in the bad sector may be lost while attempting to recover bad sectors.
You may also try creating a new user account and check if the issue recurs in the newly created account.
If in the new user account, the issue does not persist; it indicates that your old user account could have gone corrupt.
Access the link below and follow the steps to repair the corrupt user profile:

Hope this helps.
