    Issues: 1) PC won't shutdown even hold down power button for long time. Only unplug power cable will shutdown pc.
    2) No signal to monitor.

    On/Off button actually will turn on power to pc, but won't shut down pc.

    Hardware: Cyberpower FX6300. 8gig of Ram.

    What I had done: 1) Instead of connecting monitor to video card, I connected it to motherboard DVI and HDMI port but still no signal to monitor (after I removed the video card).
    2) Followed some instructions from youtube but still no signal to monitor.
    3) Switched another monitor but same result.

    Any help or suggestions are greatly appreciated

    First Name:
    The shutdown by holding the power button is a function of the motherboard (BIOS). The lack of video would indicate that the computer isn't actually booting (ie: completing POST).

    So there is likely a hardware fault of some sort. Try clearing the CMOS.

    Otherwise, use the troubleshooting sticky to determine the actual hardware fault: https://forums.techguy.org/threads/troubleshooting-guide-for-problem-builds.580000/
