Hi DanielBurke7,
Based on the description, this problem seems be caused by system upgrades.
Please try the method bellow to help solve the issue.
- Repair Online: Start< Control Panel< Programs and Features. right click Microsoft Office 365 and click on change->Online Repair->Repair; It takes a little longer time, and please keep online.
- In order to avoid the effects of third-party software, please try Excel in Safe mode.
- If the issue still exists, please update your graphics driver to see the outcome.
It would be better if you tell us the OS version and Excel version for the further assistance.
Regards,
Jerry
