Windows 10: My PC shuts down randomly in 5 minutes of turning it on

Hello,


Since the last month, my PC would only display a black screen after being inactive for some time, and not wake up. I did not pay much heed to this problem as I seldom leave it on sleep mode or inactive. On the few occasions that I did so I had to directly unplug it and then restart.


However, since the last few days, it has been acting very peculiarly. It barely stays on for 5 minutes after turning it on. Does not really shut down properly, the screen just goes black and I cannot do anything with it. The CPU continues to show the power button light on. I tried restarting in safe mode but the problem persists. Sometimes, it dies at 5 minutes, sometime in 2, and sometimes even in the process of booting up. The boot up screen shows different messages and screens at different times. Sometimes it flashes a single dash on the top left corner screen before proceeding with boot up, sometimes "preparing automatic recovery" and "diagnosing your PC", sometimes the troubleshoot screen.



What's more peculiar is that this problem is not consistent. It first happened on Friday morning and I could not get my computer to work for a long time. But then it started and worked well for a couple hours on Friday night and then all of Saturday 10-12 hours. The problem happened again on Sunday morning. After 15-20 tries, the computer started functioning in the afternoon and worked well till I turned it off at night. And today is Monday, and it won't work again. Tried almost 15-20 times again.


Not sure if relevant but some more info: Installed a Windows update on Sunday morning during one if the 5-min sessions. Also, it has been raining very heavily since 3 days here, wondering if that could have caused the problem.



Please help. Thank you.

:)

 

Laptop randomly shuts down after latest Windows 10 update

Since the latest update of Windows 10 my computer decides to randomly shut down after every couple of minutes. First the screen goes black, then the sounds stops and after quite a while the power also goes down.

Obviously I though of cleaning the fan with a big vacuum, as suggested on My Windows 10 Computer Randomly Shuts Down . However, after doing this, the shutting down goes even quicker. I cannot even properly log-on before the shutdown takes place.

What should be my next step?

Ps. The computer is quited aged (roughly 3 - 4 years). The battery is dead enough such that I always need to have it plugged in an outlet. It might just be "done for" but I'm hoping to revive it for just a little bit more.

 

HP Pavilion 15 randomly shuts down incorrectly if fast startup enabled

I've just updated an HP Pavilion 15 from Windows 8.1 to Windows 10 (Home 64 bit). If fast startup is enabled, the laptop freezes at the very least step of the shutting down process. The shutting down process goes like this:

1. First you click on shut down
2. The shut down screen appears
3. The screen turns off and then the fan starts to spin at high speed
4. After 4-5 seconds, the fan stops
5. The laptop is completely turned off, no lights are turned on (in most of PC's)

Well, my problem is that randomly, the Pavilion 15 freezes after step 4 has been completed, with the light of the ON/OFF button turned on forever. Sometimes it turns off correctly, but many other times this happens. If I disable the fast startup, this won't happen and it will always turn off correctly.

What can I do?
How is it that it's random?

I've tested this with no apps running on background, so that can't be the reason, besides, no apps or programs can freeze the system after the step 4 has been completed, since they are all shut down after step 1.

Also, the fast startup option was activated when I was using Windows 8.1 and never had a single problem with this laptop.

 

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.
