Question

1. a customer wants to upgrade their pc to support a newer cpu model, but when installed, the system fails to post. what should the technician verify first? a) the power supply wattage b) the bios version on the motherboard c) the video card drivers d) the amount of installed ram

Explanation:

When upgrading a CPU, the BIOS (Basic Input/Output System) on the motherboard needs to be compatible with the new CPU model. If the BIOS version is too old, it may not recognize the new CPU, causing the system to fail POST (Power - On Self - Test). The power supply wattage (A) is more relevant when adding power - hungry components like a high - end graphics card. Video card drivers (C) are for the graphics card and not directly related to CPU compatibility. The amount of installed RAM (D) is about system memory capacity and not CPU recognition during POST.

Answer:

B. The BIOS version on the motherboard
