What this error means
This Windows stop screen appears when your PC hits a serious system problem and needs to restart to protect itself. It often shows up during startup, after a driver change, after installing updates, or while using a specific app or device. If it happens once, it may be temporary. If it keeps coming back, something on the PC likely needs attention.
Common causes
- 1A faulty driver or recent driver update
- 2A Windows update that did not install cleanly
- 3Corrupted system files or a damaged app
- 4Failing hardware, such as memory, storage, or overheating
How to fix it
- Restart the PC and note what happens. If the screen appears only once, give Windows another try. If it repeats, pay attention to whether it happens at startup or after opening a certain app or device.
- Remove any recent changes. If you recently installed a new app, driver, or peripheral, disconnect the device or uninstall the app if possible, then restart and check again.
- Start Windows in Safe Mode. Safe Mode loads only the basics, which can help Windows start without the problem driver or app. If the PC is stable there, the cause is often a driver, startup app, or recently added software.
- Install any pending Windows updates. Updates can fix known stability problems. Go to Settings > Windows Update and install everything available, then restart.
- Free up space and remove temporary clutter. Low disk space can make Windows unstable during updates and heavy use. Delete unneeded files, empty the recycle bin, and clear temporary files if your storage is nearly full.
- Check system files and device drivers. If the problem continues, use built-in repair tools to look for damaged Windows files and update your drivers from the manufacturer’s support page, especially graphics, storage, and network drivers.
- Scan for malware and back up important files. Run a full security scan, then save important documents, photos, and other files to OneDrive or an external drive in case the issue becomes more serious.
