Ensure they're seated correctly before closing the panel and powering on the system.
If your Dell OptiPlex 5055 is not powering on, check the power cable connection and ensure it is securely plugged into both the outlet and the PC. Try a different power outlet or cable if available.

To clean dust from your Dell OptiPlex 5055, power off and unplug the computer.
