Malware, viruses, or system crashes can corrupt essential files and settings, leading to a black screen.

Incorrect BIOS settings, such as an incompatible display resolution, can cause the screen to remain black.

Inspect the display cable and ensure it’s securely connected to both the motherboard and the screen.

Access the BIOS settings by pressing the appropriate key (usually F10 or F2) during startup and reset the settings to default values.
