1. a technician is diagnosing a motherboard that emits no beeps and shows no power lights when the power button is pressed. which of the following steps should be performed first? a) check for a short between the motherboard and case b) replace the cpu immediately c) reset the cmos by removing the battery d) swap out the hard drive

Explanation:

When diagnosing a motherboard with no power and no beeps, the first step is to check for physical issues like a short circuit. A short between the motherboard and case can prevent power - on. Replacing the CPU (B) or resetting CMOS (C) are later steps. Swapping the hard drive (D) is unrelated to power - on issues.

Answer:

A. Check for a short between the motherboard and case
