Dear Mary Katherine Blohm,
Thank you for your question and for sharing the details into Microsoft Q&A Forum.
I understand how frustrating it can be when the screen saver works on one Windows 11 PC but won’t start on another, even with the same settings. At this point, I recommend that you review and try the steps provided in both the AI generated answer and the Independent Advisor’s answer on your thread. Those replies typically include the most relevant checks for this scenario. To help narrow this down and provide the next step, could you please share a bit more information?
- Does the screen saver run when you click “Preview”?
- What is the Wait time set to (e.g., 1 minute / 10 minutes)?
- In Settings > System > Power & battery > Screen and sleep, what are the values for: Turn off my screen after and Put my device to sleep after
- Does the issue still happen if you leave the PC on the Desktop with all apps closed (no video, no full-screen apps)?
- Is this PC managed by an organization (work/school account, domain, company policy)?
- Any USB devices connected (wireless mouse receiver, controller, docking station)?
- Please share your Windows build by running Win + R >
winver(Version + OS Build).
In the meantime, here are a few basic steps you can try:
1.Confirm basic screen saver settings
- Go to Settings > Personalization > Lock screen > Screen saver
- Set Screen saver to Blank (for testing) and Wait can set to 1 minute
- Click Preview (confirm it displays)
- Click Apply > OK
- Leave the PC untouched for 1–2 minutes and check if it starts.
2.Make sure Screen/Sleep timing is not preventing the screen saver
- Go to Settings > System > Power & battery > Screen and sleep
- Temporarily set for testing Turn off my screen after 10–15 minutes and Put my device to sleep after 15–30 minutes
- Keep Screen saver Wait at 1 minute and test again.
3.Check for apps
- Close any apps that might keep the PC active (video playback, Teams calls or screen sharing, games, remote desktop sessions).
- Leave the PC on the Desktop (no full-screen content).
- Don’t touch keyboard/mouse and see if the screen saver starts.
4.Rule out input devices generating small movement
- Disconnect non-essential USB devices (especially wireless mouse receiver, controllers, docking station accessories).
- Test again with only a basic keyboard/mouse (or even temporarily without the mouse).
5.Clean Boot test
- Press Win + R, type
msconfig, press Enter - Services tab > check Hide all Microsoft services > click Disable all
- Startup tab > click Open Task Manager > disable all startup items
- Restart the PC and test the screen saver again
6.Update drivers and restart
- Go to Settings > Windows Update > Check for updates
- Then open Advanced options > Optional updates > Driver updates
- Install any available Display/Graphics, Chipset, and HID/Mouse/Touchpad driver updates
- Restart the PC and test the screen saver again
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.
I hope these steps help your Windows 11 screen saver start normally again. Wishing you a smooth experience in getting the screen saver working as expected so you can use your device without interruptions.
