Surface 3 randomly restarts

My surface randomly restarts, although I cannot pinpoint a particular situation when this occurs. Sometimes it restarts when sleeping, other times when I'm on a website and sometimes when working on files. I am usually plugged in so don't think it's battery related. Task manager shows 76% with 1 web page open.

I have tried a couple of registry cleanups mentioned on forums, have ensured all updates are installed, have run the surface diagnostic toolkit, have uninstalled and re-installed peripherals, performed forced shut downs etc to no avail.

Suggestions?

    Hi Dale Hannaford,

    Random restarts can be particularly disruptive when they occur during unrelated activities, and I appreciate the detailed list of troubleshooting steps you have already completed.

    At this point, I recommend that you review and try the steps provided in the AI generated answer on your thread. That reply typically include the most relevant checks for this scenario. 

    Since the updates, Surface Diagnostic Toolkit, peripheral reinstallation, and forced shutdown have not helped, I would avoid repeating those steps for now. I would also recommend not making any further registry changes, as they can introduce additional instability. If possible, please let me know which registry values were changed.

    To narrow down the cause, could you check the following?

    • Press Windows + R, enter winver, and share the Windows version and OS build shown.
    • Let me know whether the Surface displays a blue screen or error message before restarting, or whether the screen simply goes black and the device starts again.
    • Search for View reliability history and check for a red X at the time of the most recent restart. Select the event and share the failure name or error details shown.
    • In Task Manager, please confirm whether the reported 76% usage is for CPU, Memory, or Disk, and which process is using the most resources.
    • Run Windows Memory Diagnostic by searching for it from Start and selecting Restart now and check for problems.

    You can also run the built-in drive check by opening File Explorer, right-clicking Windows (C:), selecting Properties > Tools > Error checking > Check. Microsoft includes both the memory and drive checks in its Surface troubleshooting guidance: Windows doesn’t respond or stops working on Surface.

    Please back up any important files while the Surface is still accessible. While my initial response may not fully resolve the issue, I truly appreciate your cooperation as we work together toward identifying the most effective solution. Thank you so much for your understanding.

    Try these steps in order, since updates and the Surface Diagnostic Toolkit were already tried:

    1. Disconnect everything external from the Surface 3. Remove USB devices, SD cards, external displays, Type Cover, and docking accessories. Then test again. Accessories can prevent normal startup or contribute to instability.
    2. Make sure the device is fully charged with the correct Surface power supply. Plug it in for at least 15 minutes, then try again. If the charger LED is blinking, flashing, or off, that points to a power-supply issue rather than Windows.
    3. Use the keyboard wake shortcut when it appears frozen or unresponsive. Press Windows logo key + Ctrl + Shift + B.
    4. Force a restart using the method for earlier Surface models. Because Surface 3 is an earlier model, press and hold volume-up + power at the same time until the screen turns off (about 15 seconds), then release both. Wait 10 seconds, then press and release the power button to turn it back on.
    5. If the device starts after the restart, check for updates again in the Surface app. In the Surface app, expand Help & support and select Check for updates to open Windows Update. This is still worth doing after an unexpected restart issue.
    6. If the problem continues, run the Surface Diagnostic Toolkit again or the Surface Repair Tool. Open Start, search for Surface Diagnostic Toolkit or Surface Repair Tool, then follow the on-screen steps.
    7. If the restarts continue after that, move to recovery or hardware service.
      • Start the Surface using a USB recovery drive: insert the recovery USB, then press and hold volume-down while pressing and releasing power. Release volume-down when the Surface logo appears.
      • If recovery does not resolve it, use one of the available service options: self-repair, send to Microsoft, or in-person support.

    Note: registry cleanups can introduce additional instability, so avoid further registry changes while troubleshooting.
