    PC Freezes randomly and completely (Version 1903, OS Build 18362.836)


    I've had this problem for about a week where my PC freezes completely, without any warning stuttering or anything. If I have a buffered video playing the sound may continue for a while, but mouse doesn't move and PC doesn't respond to anything. I've tried to wait a minute or two, but it doesn't seem to have a difference. So far I haven't been able to catch anything in the event viewer since the PC freezes so fast that it doesn't seem to have a chance to write anything up. I tried /sfc scannow but it didn't find any errors. Also tried updating drivers and Windows 10.

    So far it seems to happen when I have blender and/or photoshop running. Haven't had a freeze when gaming or just browsing the internet. Since I have no error to work with it's really hard to google some solutions so I'm at a loss.

    Any suggestions?

    Hi this seems to be from around 2017, so not so old.

    I've had this problem for about a week
    History: (so often omitted by posters)
    - Please check your Update History- was any update or (at the bottom) driver update applied around then?
    - Did you install or update any programs? (Control Panel, Programs and Features lists dates)
    - or uninstall any?
    - Did you make any hardware changes?
    - Was there any attributable event- power outage, cat walked over keyboard....?

    As you say, freezes don't leave tracks in terms of logs or error messages.

    Look first to hardware. Run the following checks:
    Disks: On each run HDTune (free) v2.55 from e.g. Softpedia: Health and Error scan tabs.
    RAM: Perform checks:
    MemTest86+ - Test RAM
    Run Windows Memory Diagnostics Tool in Windows 10

    Pick some stress tests:
    Huge List of Computer Stress Test Software [Used by Engineers in the Rugged Computing Industry]

    Enable and Disable Driver Verifier in Windows 10

    Bear in mind some find this problem could be PSU related.

    Software: try a clean boot (Google if unsure how or see tutorial).
    Run for long enough in a manner that indicates whether yor PC freezes or not.

    So far it seems to happen when I have blender and/or photoshop running.
    - probably RAM intensive? Are these fully compatible with Win 10?

    Whilst you could use MS's Process Monitor (Procmon) to capture a log of all activity - which would presumably cease at the point of freezing- unless the freezing was consistent with some particular action, I doubt you'd learn anything. And even it there was any consistency, making a deduction from that could be next to impossible.

    Once you've done the disk check, try disconnecting any disk you don't need to have present in a typical freezing scenario and see if there's a freeze.

    If disk checks all pass, also try
    Hard Disk Sentinel (trial) (SSDs too) and check the tab for each disk. That's the most informative program I know of.

    Hello dalchina, thanks for the quick response.

    Unfortunately I can't recall the first time this happened since I thought it as one off scenario and didn't mind it too much. The only update that seems to vaguely hit the timeframe is 2020-01 Update for Windows 10 Version 1903 (KB4497165), which I installed on 28/05/2020. There have been no hardware changes and I don't think there have been any power outtages or any of the sorts.

    As for Blender and Photoshop, they can potentially use up a lot of RAM but I don't think that was the problem on this occasion, since the files I worked with have been quite simple and light. Probably the program which uses the most RAM is the Firefox, since I sometimes work with multiple tabs, but I didn't notice the usual stuttering or slowing down when running out of RAM. Both Blender and Photoshop should be the latest stable versions and compatible with Win10.

    I'll try out the different checks and tests, and get back to you.

    Sorry to reply so late, the freezing is way too random to reproduce effectively so I wanted to take my time with this.

    I uninstalled the latest windows update and I haven't had a freeze yet. The tests didn't come up with any errors whatsoever so either I've been incredibly lucky (which is not impossible considering how randomly the problem occurred) or it actually was the windows update that caused it.

    Either way it looks like the problem has been solved for now? Thanks for all the help. Should you prefer that I mark this up as solved and if I require further assistance with the problem I create a new thread?

    That's good, but leaves a potential problem pending with any next update - which is cumulative, so would encompass this one.

    You can of course block (hide) that particular update - tutorial available or free 3rd party tool.

    Yeah, I was worried about that and I'm not that fond of skipping on windows updates on general, for obvious reasons. Is there anything you'd recommend in a situation like this?

    If you can find any correlation between freezes and one particular program that would be great, then check compatibility/version of that program and any reports of similar issues.

    Otherwise hide the update for now, and be prepared to cope with the same on any next update.

    If you can run without freezes for 'long enough' that helps to give confidence it's not hardware-related.

    Well it froze again, so it seems it's not the update after all. It just took about a week in between to crap out again. If it's not hardware related, it's probably blender, since it has been running every time the PC froze. Seems a bit random that it would start freezing without being updated or anything though, but it is constantly in development and has quite a few bugs. Haven't seen anyone report identical problems, but there was one report of PC rebooting when using blender, although they were suspecting hardware problems too.

    I'm guessing I have to run more tests and try the clean boot method quite a bit longer so we can slowly rule out the background programs and the hardware.

    I have a feeling this might take a while.

    Yes- patience can be its own reward- just a steady process of elimination...

    Did you uninstall the Display adapter driver in Safe Mode? A good method is to use Display Driver Uninstaller [DDU] and to install the driver version ,or later,as listed on the Display page in---dxdiag---and only from the nvidea site.
    If you suspect Blender as a problem,then remove it,there are alternatives available on---alternativeto.net---
    Could you confirm there aren't any entries in Reliability History?
