Hi Bill McNaney,

1. Since when are you facing this issue?
2. Were there any changes made prior to this issue?

Step 1:

Check if the Disk Defragmenter service is running.
a. Click Start and type services.msc in the search box.
b. On the Services window,  look for Disk Defragmenter service and Click OK.
c. Check if the status of the Disk Defragmenter service is set to Automatic.

Step 2:

Put the computer in a clean boot state and check if the issue persists.
a. Putting your system in clean boot state helps in identifying if any third party applications or startup items are causing the issue.
b. Refer the following Microsoft KB article for more information on how to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7:
How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7?
Note: After troubleshooting, make sure to put the computer to start as usual as mentioned in Step 7 in the above KB article.

Step 3:
If the issue still persists, run System File Checker tool [SFC] Scan and check if it resolves the issue.
Use the System File Checker tool to determine which file is causing the issue, and then replace the file. To do this, follow these steps:
a. Open an elevated command prompt. To do this, click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator. If you are prompted for an administrator password or for a confirmation, type the password, or click Allow.
b. Type the following command, and then press ENTER:
The sfc /scannow command scans all protected system files and replaces incorrect versions with correct Microsoft versions.
More Information about SFC scan can be found in this document:

Step 4:
Also check Event Viewer entries to find the faulty module that could be causing this issue.
a. Open Event Viewer by clicking the Start button, clicking Control Panel, clicking System and Maintenance, clicking Administrative Tools, and then double-clicking Event Viewer.
If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
b. Click an event log in the left pane.
c. Double-click an event to view the details of the event and let us know the faulty module that is causing the issue.
