If your computer has power but isn't booting, the issue could be with the hardware or the BIOS settings. First, check if all cables are properly connected and if the power supply is functioning correctly. Next, examine the RAM sticks; they might need reseating or replacing if faulty. Also, consider resetting the BIOS/UEFI settings to default, as incorrect settings can prevent booting. If the problem persists, it could indicate a more severe hardware issue, such as a faulty motherboard or processor, requiring professional assessment.
