    Hi Faf6432,

    If your Acer Veriton X4240G powers on and the CPU fan spins, but your keyboard, mouse, and monitor stay off, it sounds like the system isn't completing POST (Power-On Self-Test). That can happen if the motherboard isn’t sending power to USB ports or video output.

    Try this first:

    1. Unplug everything and hold the power button for 30 seconds (with no power cable connected).
    2. Clear the CMOS by using the jumper method or removing the coin-cell battery for a few minutes, then reinstall it.
    3. Boot with just one RAM stick, no drives connected, and no PCIe cards—just the bare minimum.

    Also check:

    • If there are beep sounds or diagnostic LEDs, they can give clues.
    • Make sure both the 24-pin power and CPU power cables are seated properly.

    If still no power to USB or monitor, the issue may be with the motherboard’s power regulation circuits or chipsets. Let us know what you see after trying the steps above—we’ll help guide you from there.

    Before you give up

    Remove the battery, unplug AC.

    Let sit overnight to reset, , reinstall battery & AC. Hopefully It'll reset.
