PC doesn't power down after holding power button for 4 seconds

The power button on a PC is temporary push switch. It makes contact as long as you hold the button down. Quick press and release triggers a smart relay on the MB to turn on or off, depending on default or OS state, such as cold on, sleep on, turn off, sleep off, etc. Holding the button down for a long time is a default hardware power kill switch. If it's not working, suspect the MB. Reset the BIOS is a good suggestion, but prolly won't work.

 

Unplugging power cord and holding the power button. PC won't turn on

Okay so I attempted to fix a Windows 10 usb problem by following a month old forum. The instructions were:

1. Unplug the power cord from desktop computer.
   
2. Hold in the on/off button for approx. 10 seconds until the light goes off. This kills the reserve power.
   
3. Unplug all of your USB cords from the back of your machine as well as any flash drive or any other USB
   device that is plugged into your computer.
   
4. Insert the power plug back into your computer and power it up. Allow it to completely load everything
   that it needs to before you do anything else.
   
5. Now start plugging your USB devices back into your computer one at a time while waiting for them to
   indicate that they are recognized. Do this with each one of your devices until all have been recognized.
   
6. Now right/click on computer or This PC and choose Manage / Device Manager /USB Serial Controllers and
   check to see if any of them have the yellow tag. They should not have if the problem is corrected.
   

Unfortunately I only got to Step 4, when I press the power button nothing turns on. So now I'm at a complete loss. The only thing that seems to turn on though, would be the lights to my led keyboard when I plug it in. Anyways, how do I fix/turn on my PC again?

Have to manually turn pc off with power button before it boots correct

Hi guys,

every time I want to use my custom-built pc (Windows 10), the process goes as following:

-press power button
-wait for initial booting to start, before a noise that sounds like something being stopped
-hold down power button so it turns off
-press power button, and voila it works.

does anyone know why this could be happening? a friend suggested a clean reinstall, i've tried a partial one with the feature that allows you to keep files and that didn't fix it.

thanks
