Windows 10: why does my computer display keep shutting off and turning back on?

its been doing this for the past couple days. i dont know whats going on with it. it randomly does it, and sometimes i have to restart my laptop just to get it to stop.

Computer is shutting down immediately after turning it on?

This has started to happen recently and I'm worried. It does not happen always but this week it happened more often. Basically when I am turning my computer on, after a beep it's shutting down. With the second time it turns on and it does not list that my computer shut down suddenly, so to get me into safe mode, etc. but it boots normally.

I am not sure what the problem is. I removed an additional small fan I had, since I always had it there in the usb, so I thought it could be causing it, but I removed it. I decided to replace my power adapter, since other times I had problem with that & usually they are heating a lot. I bought a cheaper adapter & still the same. I also noticed that this problem usually happens when I turn on my computer after hours. I tried to turn on/turn off my computer between minutes and it did not happen.

Could it be dust? The CPU? I just hope there isn't any problem with the motherboard.

 

Turning on/shutting down issue

Hello,
I cannot turn on my PC at all until I unplug something, like when I try to turn it on it doesn't work, I unplug the Display port then I turn it on and after it turns on I replug it.
I also have problems with shutting down, I sit the pc down from Windows and it shows me the "shutting down" thing and then it suddenly shuts off like it's been unplugged from the wall.
I have my AC, phone, monitor, router and PC.
And I'm using some extensions and adapters because the wall plug is pretty far.
By the way I replaced my Mobo CPU, ram and GPU because the previous build had other problems.

Thanks in advance.

 

Computer turns itself back on after shut down

Hi Thiaunaj,

It could be due to incorrect settings or missing/corrupt drivers or missing updates.

I suggest you to try the steps provided below and check if it helps.

• Go to, Settings. Then System. Then click on Power and Sleep.
• Click on Additional power settings. Then "Choose what the power button does".
• Click on Change Settings. Finally unclick "Turn on fast start up".
• Save Settings.

Also, try to run the Power Troubleshooter.

Power troubleshooter will automatically fix some common issues with Power Plans. Run the Power troubleshooter to adjust your computer's power settings. The Power troubleshooter checks things like your computer's timeout settings,
which determine how long the computer waits before turning off the monitor display or entering sleep mode. Adjusting these settings can help you conserve power and extend your computer's battery life.

• Press Windows Logo Key+X then click on Search option.
  
• Type Troubleshooting.
• Select Troubleshooting and click on
  System and Security.
• Click on Power and follow the onscreen steps.
