Intel NUC 8I5BEH shuts down with no warning

Hi,

My intel NUC shuts down with no warning after signing into my windows, I tried installing windows 10&11 (clean install) but experienced the same problem.

The furthest the system is able to go is past the sign in screen and it will shut down a few seconds later.

The device is however able to function in safe mode (Heavy streaming videos) without shutting down.

I updated the BIOS to latest version but didn't see change.

would appreciate some assistance as i am tired of operating in safe mode. 

 

Thanks

1. Did you checked the CPU temperatures? You may use for this free program HWinfo portable.

2. Did you installed all the necessary Intel Drivers?  The first driver to be manually  installed is the  Intel® Chipset Device Software. Only after installing this driver and rebooting NUC, you may install all other drivers (the sequence is not important).

Hi Leon

 

1. I have checked the CPU temperatures and generally find readings ranging from 48c - 60c.

2. I installed the first set of drivers following your sequence but could not install a few due to the constant shutting down of the NUC, it shuts down randomly while running as if someone pulled the power socket. 

what's strange is that it is able to run in safe mode without switching off.

Hi @theInsight 

Your NUC is shutting down - black screen, Power LED OFF and Standby LED (Item "P" on page 4 in the Technical Product Specification)? 

 rather than Windows crash (blue screen)?  To see the Standby LED you may power ON you NUC with the bottom cover removed.

or

your Windows is crashing (blue dead screen)?

Hi Again

 

My NUC is shutting down completely (Black screen, no error message, LED Off). Almost as if someone disconnected the electricity.

The only time it does not crash is when in safe mode.

You may try to troubleshoot your Windows performing Clean Boot.  You may set the Clean Boot configuration in SAFE mode and then reboot in NORMAL mode (in Clean Boot Configuration). If this work, you may continue from para. 9 in this procedure.

Edit:

Open  Computer Management and check the Windows logs to find possible indication for this shut down.

Hi Leon

 

Thanks for your assistance,

I performed a clean boot with different settings (diagnostic/selective/normal) and it seems the NUC doesn't care which i choose as it still shuts down randomly Irregardless of which services are enabled/disabled.

Do you think this could be a hardware issue?

Also, I am still confused by the fact that it can run in safe mode without crashing at all.

1. "I performed a clean boot with different settings (diagnostic/selective/normal)...." This was done by selecting startup option from the GENERAL tab in System Configuration. Did you also restarted Windows after disabling all services except the Microsoft  on the "Services " tab (as explained in para. 5 of the tutorial?

2. Did you checked the Windows log for error causing the shut down?

1. Yes, I restarted Windows after disabling all services except the Microsoft on the "Services " tab, but my problem continues.

2. I get the following error:

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

 

3. I installed a fresh copy of Linux mint earlier and the NUC crashed when the Linux logo appeared. could this mean i have a hardware problem??

Yes, it looks like a hardware problem. In order to exclude the problem from the Power Supply, can you check with other Power Supply? For example one, borrowed from laptop.

Hi Leon,

After struggling for a very long time i managed to resolve the issue, I went into BIOS and disabled "Turbo boost", the NUC has since stopped crashing and runs as normal, do you have any idea why it crashes when turbo boost is ON?

Since you've checked that the temperatures are well withing the limits while the crash occurs, I would check the memory modules.

You may try to work with one memory module at time (in upper and lower slot) and/or using Memtest86 utility.

BTW, in some of my NUCs, I switched OFF the Turbo Boot in order to have quieter system.
