(select one.)
the power connector for the fan was not connected to the motherboard.
someone unplugged the computer without performing a proper shutdown first.
the cpu is not supported by the bios.
the cpu is bad.
the heat sink and fan were not installed correctly.

Explanation:

Step1: Analyze option 1

A disconnected fan power connector may cause over - heating issues in the long run but usually doesn't directly result in a black screen right after power - on.

Step2: Analyze option 2

Unplugging the computer without a proper shutdown might cause data corruption or boot - up issues but not typically a black screen immediately after powering on.

Step3: Analyze option 3

If the CPU is not supported by the BIOS, the system may not be able to initialize properly and can result in a black screen. When a new CPU is installed, compatibility with the existing BIOS is crucial.

Step4: Analyze option 4

A bad CPU can cause the system not to boot, resulting in a black screen. But usually, there would be some error beeps or other indicators in some cases.

Step5: Analyze option 5

Incorrect installation of the heat sink and fan can lead to over - heating, but usually not an immediate black screen right after power - on.

Answer:

The CPU is not supported by the BIOS.
