Hi KW67,
In order to troubleshoot the issue better, please provide more information.
How long have you been experiencing this problem?
Have you recently installed or uninstalled any software or hardware?
Are you logged in as Administartor?
I would suggest you to boot the computer in Safe Mode and check if the issue still persist.
Safe mode is useful for troubleshooting problems with programs and drivers that might not start correctly or that might prevent
Windows from starting correctly.
1.
Remove all floppy disks, CDs, and DVDs from your computer, and then restart your computer.
Click the
Start button, click the arrow next to the Shut Down button, and then click
Restart.
2.
Do one of the following:
·
If your computer has a single operating system installed, press and hold the F8 key as your computer restarts. You need to press F8 before the
Windows logo appears. If the Windows logo appears, you'll need to try again by waiting until the
Windows logon prompt appears, and then shutting down and restarting your computer.
·
If your computer has more than one operating system, use the arrow keys to highlight the operating system you want to start in safe mode, and then press
F8.
3.
On the Advanced Boot Options screen, use the arrow keys to highlight the safe mode option you want, and then press Enter.
4.
Log on to your computer with a user account that has administrator rights.
When your computer is in safe mode, you'll see the words
Safe Mode in the corners of your monitor. To exit safe mode, restart your computer and let
Windows start normally.

If the issue does not persist then I would suggest you to run System File Checker.
1. 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
clickAllow.
2. Type the following command, and then press ENTER:
sfc /scannow
The
sfc /scannow command scans all protected system files and replaces incorrect versions with correct Microsoft versions.
