A motherboard is a computer component that connects various parts of the computer system, including the CPU, memory, storage, and expansion cards. If the motherboard fails, the computer will not be able to function properly. There are a few things you can do to check if your motherboard is dead.
First, check to see if the computer is receiving power. If the power supply is not providing power to the motherboard, the motherboard will not be able to function. You can check the power supply by using a multimeter to measure the voltage output.
