2. Carefully remove the bottom panel as described in the RAM upgrade section.

4. Use a clean, non-oily "Natural Gum" eraser to gently clean the gold contacts on the RAM modules. Alternatively, use isopropyl alcohol and a microfiber cloth.
5. Use a soft brush or compressed air to clean any dust from the RAM slots on the motherboard.
6. Reinsert the RAM modules, ensuring they are seated correctly.
7. Reattach the bottom panel and reconnect all cables.

4. Troubleshooting

4.1 System Not Booting or Freezing

If your Mini PC experiences issues like not booting up, freezing, or graphical glitches, especially in humid or dusty environments, RAM issues are a common cause. Refer to the "Cleaning RAM Modules and Slots" section under Maintenance.

After cleaning and reinserting RAM, test the system. If problems persist, try the following:

• Test one RAM stick at a time: If you have multiple RAM modules, try booting the system with only one module installed. If it boots successfully, test each module individually to identify a faulty one.
• Try different RAM slots: If a module doesn't work in one slot, try it in another known-good slot.
• Run a memory diagnostic: Use the built-in Windows Memory Diagnostic tool or a third-party tool like MemTest86 to check for RAM errors.

4.2 Operating System Issues

If you encounter operating system issues (e.g., missing apps, installation errors), a clean reinstallation of the OS is often the most effective solution. Refer to the "Operating System Installation" section under Setup.
