First, make sure you have all the necessary tools and supplies to repair your computer. You may need a screwdriver, an antivirus program, a backup drive, and a copy of Windows 10 or another operating system. Once you have those things, follow these steps to start fixing your computer: 
1. Turn off the power on your computer.
2. Unplug any external devices from your computer such as USB drives, printers, and monitors.
3. Remove any screws or covers that are covering up the ports on your motherboard.
4. Check for dust buildup around the CPU socket. Clean it if there is any.
5. Check the power supply unit (PSU) cables and connections.
6. Make sure the RAM modules are properly seated in their slots.
7. Check the hard drive cables and connections.
8. Test your keyboard and mouse connection to make sure they're working correctly.
9. Install the new RAM if needed.
10. Reinstall the CPU cooler if applicable.
11. Reconnect all external components.
12. Power on the computer and check for any errors.
