My PC lags if I don't force shutdown by holding the power button

My version number is 19042.867

This is what happens:
If I normally shut down the PC through the Windows panel, when I turn it on again it lags.
By lagging, I mean that every second, it freezes for a few frames. But not only the screen, audio as well.
The only way for that not to happen is if I hold down the power button on my desktop until it forces shut-down.
I'm pretty newbie at this, so if you need any logs or something like that, just let me know how to get them.

 

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?

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.
