Device Has Stopped Responding: What It Means & Fixes

When your computer, phone, or other gadget freezes and shows the message “The device has either stopped responding or is…” it means the operating system can no longer communicate with that piece of hardware, and the most direct fix is to restart the device or the software that manages it. This article explains what causes that error, how to recover from it, and how to prevent it from happening again.

What the Error Message Actually Means

The full message usually appears in Windows as: “The device has either stopped responding or is unresponsive. Please wait a moment and try again.” It is a generic warning from the operating system’s Plug and Play manager or Device Manager. It does not tell you which device failed, only that a hardware component did not answer a command within the expected time. The same idea appears on Android as “System UI isn’t responding” and on macOS as “Application not responding” — but the underlying cause is similar: a driver, a hardware conflict, or a resource shortage.

This message is different from a blue screen or a full system crash. The OS is still running; it just lost contact with one piece of hardware, such as a USB drive, a graphics card, a network adapter, or an internal storage drive. In many cases, the device recovers on its own after a few seconds. If it does not, you need to intervene.

Common Causes of a Stopped Responding Device

• Outdated or corrupted drivers — the most frequent cause, especially after a Windows update or a new hardware install.
• Power management settings — the OS puts the device to sleep to save power, then fails to wake it properly.
• USB port or cable issues — a loose connection, a damaged cable, or a port that cannot supply enough power.
• Hardware overheating — a GPU or SSD that gets too hot may stop responding until it cools down.
• Resource exhaustion — too many programs open, or a memory leak, can starve the device driver of system resources.
• Firmware bugs — the device’s own internal software has a flaw that causes it to hang.

These causes are not mutually exclusive. A laptop that overheats while charging a phone through a worn USB cable can show the error even though the phone is fine.

How to Fix It: Step by Step

Try these in order, from least disruptive to most thorough. Stop when the device works again.

1. Wait 30 seconds. The system may be retrying the connection. Do not unplug anything yet.
2. Unplug and replug the device. For USB devices, use a different port if possible. For internal devices, skip this step.
3. Restart the computer. This clears most temporary driver and resource issues. Choose Restart, not Shut Down, because Windows Fast Startup can skip a full reset.
4. Run the Hardware and Devices troubleshooter. In Windows, go to Settings > System > Troubleshoot > Other troubleshooters and select Hardware and Devices.
5. Update the driver. Open Device Manager, find the device (it may have a yellow warning icon), right-click it, and choose Update driver > Search automatically.
6. Uninstall and reinstall the driver. In Device Manager, right-click the device, choose Uninstall device, then restart the computer. Windows will reinstall the driver automatically.
7. Disable power saving for the device. In Device Manager, right-click the device, choose Properties > Power Management, and uncheck “Allow the computer to turn off this device to save power.”
8. Check for Windows updates and firmware updates. Some device issues are fixed by a system update or by a firmware update from the device manufacturer.

If the problem persists after all these steps, the hardware itself may be failing. Try the device on another computer to confirm.

How to Prevent It From Happening Again

Prevention is mostly about keeping drivers current and avoiding resource overload. Set Windows Update to install driver updates automatically, or check the manufacturer’s website for your specific device model. Avoid using cheap or damaged USB cables for high-power devices like external hard drives. Keep your computer’s vents clear and clean dust out of fans every few months.

Another practical step is to disable Fast Startup in Windows if you frequently see the error after booting from a cold start. Go to Control Panel > Power Options > Choose what the power buttons do, then uncheck “Turn on fast startup.” This forces a full shutdown each time, which can prevent driver state corruption.

If the problem only happens with one specific device, like a printer or a webcam, check whether the device has its own power switch or a separate power adapter. Some devices need more power than a USB port can provide, and a powered hub solves that.

When the Error Is on a Phone or Tablet

Android and iOS devices show similar messages, but the fixes differ slightly. On Android, a “System UI isn’t responding” or “Google Play services keeps stopping” message usually means an app or the system UI crashed. First, force-stop the offending app from Settings > Apps. If that does not help, restart the phone. If the problem repeats, clear the app’s cache or update the app.

On an iPhone or iPad, an app that “is not responding” can usually be closed by swiping up from the bottom and swiping the app away. If the whole device freezes, force restart it by pressing and quickly releasing Volume Up, then Volume Down, then holding the side button until the Apple logo appears. This does not erase data.

What Not to Do When a Device Stops Responding

Do not yank out a storage device while it is actively writing data — you risk file corruption. If the device is an internal SSD or HDD, do not repeatedly power-cycle the computer in a short time; wait a minute between attempts. Do not install random “driver updater” software from the internet; most of it is adware or worse. Stick to Windows Update or the manufacturer’s official site.

A common misconception is that the error means the device is broken forever. In reality, most occurrences are temporary software glitches. Only if the error appears every time you connect the device, or if the device disappears from Device Manager entirely, should you suspect physical failure.

Frequently Asked Questions

Q: Will I lose my data if I restart the computer?
Normally no, because you are restarting the OS, not erasing storage. However, any unsaved work in open programs will be lost. Save your work before restarting if you can.

Q: How do I know which device is causing the error?
Open Device Manager and look for a yellow triangle with an exclamation mark. That device is the likely culprit. You can also open Event Viewer (eventvwr.msc) and look under Windows Logs > System for errors with source “Kernel-PnP” or “USB” around the time the message appeared.

Q: Can a virus cause this error?
Yes, malware can interfere with drivers or exhaust system resources, but it is not the most common cause. Run a full antivirus scan if the error is frequent and you see other suspicious behavior.

Q: Is it safe to keep using the computer after this error?
Usually yes, but if the device is a storage drive, back up important files first. If it is a graphics card and you see visual artifacts, stop using it and check for overheating.

Q: Why does the error happen more often after a Windows update?
Updates can change how the OS interacts with drivers. A driver that worked before may no longer be compatible, or the update itself may have installed a buggy driver. Rolling back the driver (Device Manager > Properties > Driver > Roll Back Driver) often fixes it.

Q: Does this error occur on Macs?
Yes, but the wording is different. macOS shows “Application not responding” or a spinning beach ball. The causes and fixes are similar: force quit the app, restart, or update the software.
