    Was using the pc when it powered off and now it won’t poweron again although the power supply unit has power as the light is on and themotherboard light is on and the USB ports have power but the fans do not havepower as they are not turning. But when I press the power button nothinghappens.
    Any ideas as to how I can solve this issue?
    Any help will be most appreciated.

    Unplug the computer for a few seconds, then plug it back in.

    The electricity went off for a couple of seconds just a flicker along the whole street including traffic lights and petrol station.

    Anyway it turned off my pc and when I pressed the power button to power on again it wouldn’t work! Checked the power supply light and it was on. So I took the side panel off and I could see that the motherboard reset button had the light on but the fans were not turning and neither were the HDDs’. Tested the USB ports with the laptop stand which has two fans and the USB ports had power. I could not understand how some parts had power but the HDD, the fans and the pc power button did not!
    Very strange if you ask me on how some parts in the pc had power and others did not including the power button did not!

    1) Check the operating system and the drive file system by running administrative command prompt commands:
    2) sfc /scannow
    3) dism /online /cleanup-image /restorehealth
    4) chkdsk /scan
    5) If there are any integrity violations that could not be fixed then post that into the thread.
    If there are no problems with the OS or drive file system then you should be OK.
    When things are OK you can make a brand new restore point and make a backup image using Macrium:

    I have run sfc /scannow which did not find any violations,dism /online /cleanup-image /restorehealth completed successfully and chkdsk /scan Windows found no problems just to make sure all is well.

    I do have a Macrium backup and have created a restore point.

    I am now looking to invest in a UPS.

    I have looked at several and CyberPower UPS with PFC Sinewave products which they say are the better option.

    I don't know what VA rating I should go for to protect a pc with 850 watt PSU plus the 57 watt monitor so that I can shut the pc properly in the event of a power cut.


    Perhaps someone can enlighten me on the VA rating I should aim for. I would prefer a UPS which the battery can replaced.
