Computer "shuts down" at random

[Psyclon13]

Hi all!

For the past week I've been having the following problem:

Mainly while watching a movie (on VLC, Media Player, ACE Player - makes no difference), and rarely while watching YouTube, my monitor turns off, as if I've shut down the PC (it shows a "No signal, going to power saving mode" message), but all the fans are still spinning. All I can do is reset. Sometimes this is accompanied by white noise on the speakers, sometimes there is no noise. Sometimes this happens suddenly, sometimes the screen goes off and I can still hear the sound from the movie for a few seconds. Today this started happening even while browsing. This is even the third time I'm trying to post this topic, the first two times "it" happened. Overall it's happened more than 15 times today.

At first I thought it might have something to do with the video card, but today I noticed that the HDD activity LED stops blinking when this happens - so is it possible that the ssd/hdd is faulty somehow?

I've thoroughly cleaned the case, re-seated all component and re-connected all cables - nothing has changed. How can I determine if any component is faulty?

 

Here is my configuration:

Asus Z97-K

I5 4690K

16GB HyperX

Radeon R9 390

Kingston 120GB SSD

Seagate 1TB HDD

Windows 7 64Bit

Have you had a look through Event Viewer?

To check if your HDD is at fault, use crystaldisk and scan for bad sectors.

To check the CPU, remove your GPU and display with the IGPU and then run AIDA 64.

To check the GPU any Standard benchmark will do, I'd recommend Unigen Valley.

 

But it really does sound like a hardware failure.

No, first time I hear about it. Here's what I can find:

I'm guessing 50 errors and 5 criticals in the past hour is not a good thing?

 

@another random person Thanks for the suggestions, I will try them now.

You can click on the kernal-power errors and look up the codes to see if they're anything bad. Or just let your PC sit, and track the time when it "turns off" then look up the errors that happened at that time.

All of them are Event ID 41, Task Category (63). If I'm not mistaken, this just means that the PC was restarted unexpectedly?

Uh. Well that doesn't as much info as I thought

 

Might want to try @another random person's steps.

Try looking at your reliability history as well

press start - type reliability history.

If there are any red errors there, double click them to expand them, and copy/paste the info that comes up here..

 

You can also look through the yellow warnings for any driver updates or whatever that may have failed to install properly.

 

Also, are you overclocking?

Because if you are.. a bad OC that looks stable but isn't can cause random unexpected restarts.

That's a great feature that I never knew existed, cheers for that!

Yea, it's basically a dumbed down event viewer, but I find it's sometimes helpful when event viewer isn't and vice versa.

It's also a lot better for average users who may find event viewer a little daunting to sort through.

Here's a screenshot from today's history:

Details of the error:

Description
A problem with your video hardware caused Windows to stop working correctly.

 

Problem signature
Problem Event Name:    LiveKernelEvent
OS Version:    6.1.7601.2.1.0.256.1
Locale ID:    1026

 

Files that help describe the problem
WD-20180411-2130.dmp
sysdata.xml
WERInternalMetadata.xml
 

So it might in fact be the gpu? I ran Unigen Valley as suggested, the benchmark was completed without problems. What should have happened, if it had an issue?

 

And no, no OC. I wanted to try, but postponed it several times and later forgot about doing it.

Did we already suggest using DDU to wipe out that video card driver and then installing the newest version?

I used DDU and installed numerous versions of the drivers, even back to 2016 - no change. With the drivers uninstalled I've had no problems so far, which leads me to believe that in fact the GPU is at fault. However, why would the sound also stop after a crash, if it's a video problem? Even if i'm not watching a movie, just listening to music on Winamp, a crash happens, the monitor goes black and the sound stops. Is there a reasonable explanation?

This weekend I will try to borrow another card from a neighbor to see if anything changes.
