Windows 10: pc randomly shuts off and fans spin really fast

i was playing escape from tarkov when my monitors randomly shut off and my fans spun incredibly fast. I just got an i9-9900k but the temps dont go below 70 degreesfile viewer says:The system has rebooted without cleanly shutting down first.

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.

 

PC only shuts down on a second try


Hello,

I posted here yesterday asking for help on a similar problem yesterday: GPU keeps working (fans spinning) for a few seconds after shutdown - Windows 10 Forums

Basically, what happens now is as follows: When I press shutdown from start menu and the PC screen goes black at the end of it, I can hear components stopping their work, but pretty much all fans keep working (PSU fan, case fans, GPU fans). They work for 20-30 seconds and then I hear a Mobo beep (the same one you hear when you turn on your PC) and the PC boots back like it's nothing. When I reach login screen and shut down again from there, the PC fans again keep spinning after components turn off, but only a few seconds this time. The PC components then turn on and immediately turn off together with the fans.

Sorry for the poor phrasing, English is not my native language and I try my best here.

This complicated double-take shut down process only began after I disabled fast startup in Windows 10 (some guys on various forums suggested that I do that). Before I disabled them, the problem was like the one I linked to in the beginning. The whole problem started after I installed a second HDD. During the installation I also removed the GPU to allow me to fix some cables.

Besides the shut down, the PC seems to be working just fine. No crashes, no BSODs - nothing. Only this strange shut down.


Things I've already tried:

• Disabling fast startup
• Removing my second hard drive
• Changing its SATA plugs
• Changing SATA cables
• Changing HDD power connector cables
• Removing and putting back the GPU
• Updating chipset driver
• Shutting down from login menu

 

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.
