Explanation

Before handling any internal computer components - especially before removing or replacing a motherboard - the technician must ground themselves to the computer case to discharge any built-up static electricity. ESD (Electrostatic Discharge) is a leading cause of silent hardware damage; a technician who is not grounded can damage sensitive components the moment they touch them. Grounding to the case (D) is always the mandatory first step before touching internal hardware. Reseating power connections (A) or installing a graphics card (C) are premature without first ensuring ESD safety. Removing the CMOS battery (B) is a troubleshooting step, not a prerequisite to replacement.
