Why is my PC shutting down randomly?

[amoretam]

Hi there,
My PC is randomly rebooting, why such a discusting behavior?

I have no idea how to proceed. I have tried: memory configuration tests, chech disk and relocating memory modules.

Would you please join me in this journey?

Thanks

First step is check event logs to they tell us anything

 

[amoretam]

Allrite. Event Viewer. What do we need from there exactly? Should I take take a screen shot?

Thanks

In Event Viewer, you want to look at errors. Specifically you want to find errors that are causing the computer to re-start. If there are lots of errors in Event Viewer, then you may want to use Reliability Monitor to pin down the exact time and date of the shutdowns.

All system errors I see are:

The previous system shutdown at 10:13:52 AM on ‎3/‎23/‎2020 was unexpected.

The RealtekWlanU service failed to start due to the following error:
The system cannot find the file specified.

The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

The previous system shutdown at 3:55:09 AM on ‎3/‎23/‎2020 was unexpected.

The RealtekWlanU service failed to start due to the following error:
The system cannot find the file specified.

and so on.......

What Event ID is provided? Event ID 2, Event ID 41, whatever ....?

The Event seems to be blaming RealtekWlanU as culprit. This is a wireless driver, if you are NOT using wireless to connect to internet, or using NOT bluetooth with any device, then you may wish to disable this feature in Device Manager. Otherwise, try re-installing the device driver for the Realtek WLAN device.

Hi there, Thanks for fast response!
The computer used to restart itself before I installed the Realtek RTL8188CU Wireless LAN 802.11n USB 2.0 Network Adapter.

Thanks for that! That could save a lot of time, possibly looking at the wrong error message here, although it might still be related.

What about this one:

The previous system shutdown at 3:55:09 AM on ‎3/‎23/‎2020 was unexpected.
...

Can you retrieve the details and error message to this Event, please?

Hello,
Lately, once i start the computer, it inmediately shutsdown before it enters OS, and then goes to the "Windows did not Shut Cown Correctly" black window.

About the details you asked me, I could not find (strangely) exactly the one you wanted but here is the same at a different time:

The previous system shutdown at 3:55:09 AM on ‎3/‎23/‎2020 was unexpected.

Unfortunately the message does not say what caused the Error,

Lets try a different tact, is the Motherboard BIOS Firmware up-to-date? You can check the Firmware version using System Info.

Hi there, you can see my BIOS version in the picture attached.
I went to the Intel page but support for this mobo is discontinued.

I had a BIOS downloaded but I am not sure if it is the latest,.
This is the name of the file: BLH6710H.86A.0160.EB

Thanks a lot

 

[iko22]

Hi,
It looks as though Intel have discontinued support for their older devices: Intel to remove old drivers and BIOS updates from its site by the end of the week | ZDNet

You can, however, find a download for Intel DH67BL Desktop Board BIOS 0163 at Softpedia. The page contains the Intel instructions, and at the bottom of page, is the download tab. The site is reliable enough.

This is DONE!

Thanks a lot.
Now I'll watch how it behaves!

 

[amoretam]

Ups, same behavior, computer inmediately self restarted on first boot. And now it did it again

What would be next?

 

[file3456]

How old is the power supply? Could be that, but I'm not sure.

Something else it could be is a malfunctioning power button that might trigger a shutdown Could even be the restart button. Investigate that.

What I would do is reconnect the headers. Then if the problem still exists, try to jump th board manually by shorting the green PSU wire with a black PSU wire. This is starting the computer without the power button. But pull the power button cable first so you can see if it is the power button connection or the reset button connection.

try a different power supply unit similar to the existing one.
if no improvement, it could be the motherboard is showing signs of age and some components on the board are failing and may soon need a board replacement

 

[Megahertz07]

Try the basic first.
Open a CMD window as administrator and type:
chkdsk c: /f
It will say your disk is in use and if you want to schedule to next start = Yes
Restart
Back to windows, open a CMD window as administrator and type:
SFC /scannow
