A technician theorizes that a computer's failure to boot is caused by a loose RAM module. What is the next step in the troubleshooting methodology?

Document the theory and the final outcome.

Test the theory by reseating the RAM and attempting to boot the computer.

Establish a plan of action to replace the motherboard.

A technician solved a unique issue where a user's mouse cursor was jumping because of a conflicting driver. After the fix, what is the most important reason to document this incident thoroughly?

To provide a step-by-step guide for the user

To prove the technician completed the work
