You’ve just received a computer from a remote office via next-day air delivery, and the PC appears to be in perfect shape. However, when starting the computer it beeps a few times and shows a black screen. You check the manual and find that the beep code refers to a problem with the CPU. Which of these would be the best next step?

A) Confirm that the CPU is receiving enough power by checking the power supply voltage setting

B) Boot with the Windows installation CD and run the memory check

C) Swap out the CPU and try starting the computer again

D) Make sure the CPU is seated securely

E) The computer would prefer an upgrade to first class next time
