Shutdown then Immediately Restarts

I ran the log collector and it opened a command prompt then disappeared. No report and no log files in the sub-directory from where I ran the .lnk.

Open administrative command prompt and type or copy and paste:
1) sfc /scannow
2) dism /online /cleanup-image /scanhealth
3) dism /online /cleanup-image /restorehealth
4) chkdsk /scan
5) When these have completed > right click on the top bar or title bar of the administrative command prompt box > left click on edit then select all > right click on the top bar again > left click on edit then copy > paste into the thread
7) run the log collector again and post a zip into the thread:
log collector v2-beta06.zip
8) If the above log collector does not display the folder on the desktop then run this log collector
9) Run this log collector:
BSOD - Posting Instructions - Windows 10 Forums
10) If the above 2 log collectors fail then run this command in administrative command prompt and post one drive or drop box share links into the thread:

Code:

Nada.

DM Log Collector appeared to peruse the various logs and reports in Windows. It created the folder TFdebugFiles on the desktop but File Explorer reports that file is unavailable. Neither File Explorer or XYplorer can see the folder on my desktop.

Running the command line version of what appears to be the DM Log Collector created .Zip file on my desktop which is empty.

See if Windows defender modifications will fix the problem:

I sent the unit to HP Repair. They replaced the motherboard and returned the unit to me within 7 days with no scratches or dings. All appears functional now. There must have been a bad batch of boards because numerous threads on HP Forums discuss this issue.

Thanks to all here for the assistance.

Your welcome.
Thank you for the feedback.
Download and install the HP BIOS UEFI hardware diagnostics:

Run version 6.5 on the computer so that you have a baseline.
To run the diagnostics power on the computer and repetitively click the F2 key > extensive or loop until failure testing.

That is a great idea to set the baseline. I'll do it now.

Thanks, zbook.
