Windows 10: HELP: Unexpected pc shutdown in Windows 10

Hello,This week, I experienced several unexpected pc shutdown. I have installed the app Obsidian.md https://obsidian.md in my laptop recently. It looks like it was the app that causing the crashes. I notice that Obsidian utilizes gpu for hardware acceleration. The crashes happened every time when the app was running in foreground. When I left my room for a long time and attempted to wake up my laptop from sleep mode, the laptop did not have any response. Then, I found out that the laptop was actually powered off unexpectedly.==========Setting info from AMD Radeon settings:Radeon Softwar

PC is Suffering Unexpected Shutdowns

Most important detail to me would be whether these shutdowns are sudden, in which case it's likely a short or PSU issue (capacitor aging maybe?) or graceful windows style shutdowns, which suggests software interference.

It could also be overheating components if it's a sudden shutdown. What are your thermals like?

 

PC is Suffering Unexpected Shutdowns

I had the memory running at 1866 when i first build the computer, the reason i changed it back to the MB default was that windows was reporting the RAM only running at 1333 even though i had changed it to 1866 in the BIOS. When i started to get these unexpected shutdowns i had though it might be related, but its not. I just haven't changed it back...Anyway i get the shutdowns when its at 1866 so thats not the issue. I dont have any other sticks to test. The kit is 2 sticks of 8GB.

Never this issue started 2 days after i built the computer.

There are no bare wires in the case. My house doesn't have a lot of static charge, ive had this PC at my parents house as well and still experienced the shutdowns. I guess its also worth noting the PC is up on my desk.

The PC just all of sudden shuts down, Complete black screen..not warning from windows, no BSOD. When i start the PC back up i dont see any windows recovery or anything like that, just starts up completely normal.

Thermals are normal when it shuts down aswell as when gaming. I'm going to run some of the tests mentioned above tonight so i can maybe give more detail then. I just experienced a shutdown as i was typing this...PC was not running hot and did not have high usage.

Thanks everyone for the help, unfortunately i don't have time to run the tests mentioned above. I will unplug all external devices as mentioned above when im not using the PC to see if that helps. NOTE: i have tried to unplug the 2TB hard drive to see if it helps...it did not. I will report back with the results of my tests.

-Thanks again

 

PC is Suffering Unexpected Shutdowns

I just built a new PC at Christmas and every now and again the PC is shutting down unexpectedly. It seems to happen randomly but it mostly happens when the PC is idling. It doesn't happen ever time its idling(maybe once every other day, seems to be completely random) and may not happen for days. Ive been watching a movie and had it shutdown, ive been gaming and had it shutdown. Here are the PC specs:

Asus Maximus VII Hero (latest BIOS, problem happened on older BIOS also)
Intel i7 4790k (no OC)
16GB Corsair Vengeance 1866 (only running at 1333)
be quiet! Dark Rock 3
EVGA GTX 660 ti (had this in my old system with no issues, latest drivers)
Antec 520W (had this in my old system for over 2 years with no issues)
Samsung 840 EVO 250GB (Boot drive, Windows 8.1)
Seagate Barracuda 2TB (used for my doc, video, pics ,etc..)
Fractal Design Define R4

Here is a list of things i have discovered though troubleshooting that might help narrow down the problem:

-I have been able to play demanding games without issues(only shutdown once while gaming)
-I have ran memtest for over 8 hours with no errors
-I have stress tested the entire system with no issues
-while stress testing CPU temp never goes over 70.
-I had AIDA64 installed and came across this thread which is what i though the issue was. I have uninstalled AIDA64 but the problem still exists and i no longer think this is related.
-I let the system sit in the BIOS while I wasn't using it for many days to see if it would still shutdown and it did not (could have been luck I dont know)
-The PC does not restart itself. After pressing the power button it boots normally with no error messages. When I go into the system logs I can see the unexpected shutdown.
- I tried disabling all startup programs except Norton 360 and it went a week then it shutdown

-The driver \Driver\WUDFRd failed to load for the device ACPI\PNP0A0A\2&daba3ff&2.
Source: Kernel-PnP
Event ID: 219
This warning has been showing up in the logs since i built the computer but didnt think much of it. Ive done alittle research on this and found that there is lots of other people with Asus MB's reporting this error, but none of them that i read have reported unexpected shutdowns. Do you think this could be linked to the shutdowns? This thread on the ROG forums has lots of info on the topic.

- i also see this warning in the logs: The driver \Driver\WudfRd failed to load for the device USB\VID_05AC&PID_12A8\9b9ceeb8e1be31f835c6ccec7c889d8d71f4f142.

-Another warning:
Intel(R) Ethernet Connection (2) I218-V
Network link is disconnected.

-None of these warnings are showing up right before the unexpected shutdown so i dont know if they are related at all.

Thanks for the help
