      Yes, if you add more screw holes

    • D.

      Yes, if you remove some ports

    • E.

      No!

    Correct Answer
    E. No!
    Explanation
    The correct answer is No! The reason is that ATX and BTX motherboards have different form factors and layouts. ATX motherboards have their expansion slots and I/O ports on the back, while BTX motherboards have them on the front. Additionally, the screw hole placements and power connector locations are different between the two. Therefore, it is not possible to replace an ATX motherboard with a BTX motherboard without significant modifications to the case.

    • E.

      Corrupted Driver

    Correct Answer
    D. Dead power supply
    Explanation
    If the computer won’t power up at all, with no lights or spinning drives, the most likely problem is a “Dead power supply” (Option D). The power supply unit (PSU) is responsible for converting AC power from the outlet into DC power for your computer components. If it’s dead, it would prevent the computer from powering up at all. Other options, like a dead hard drive or a corrupted driver, would typically still allow the computer to power up, but it might fail to boot or operate correctly. Insufficient wattage could potentially cause power issues, but it would be more likely to cause instability or shutdowns under load rather than preventing power up entirely.
