Troubleshoot Screen Flickering in Windows

Answer
Use Task Manager to distinguish a likely display-driver problem from an incompatible app, then repair only the matching cause.
Protect work and note when flickering occurs
Save open work and disconnect only nonessential displays or adapters. Note whether flickering starts at sign-in, after opening one app, or only on a particular monitor. If the display becomes unusable, stop repeated restarts and use a stable monitor or Windows recovery option to protect access to the PC.
Run Microsoft's Task Manager test
Press Ctrl + Shift + Esc to open Task Manager while the screen is flickering. Watch whether Task Manager flickers with everything else. Microsoft uses this distinction to choose the next path: Task Manager flickering points more strongly to a display driver, while a stable Task Manager with other windows flickering points more strongly to an incompatible app.
Follow the display-driver path when Task Manager flickers
Use Microsoft's display-driver steps in the linked guide. Depending on what changed, that can mean updating the driver, rolling it back after a recent update, or uninstalling it so Windows can reinstall it. Use Device Manager and the PC or graphics manufacturer's supported driver; do not install a random driver utility or change several display settings at once.
Follow the incompatible-app path when Task Manager is stable
Identify an app installed or updated near the time flickering began. Update that app from its publisher or uninstall the confirmed problem app through Settings. Restart and test before changing another program. Background utilities that alter the desktop or display deserve review, but do not remove unrelated software merely because it is running.
Test displays and connections separately
If only one external display flickers, reseat its cable, try another supported cable or port, and test the monitor with another source when practical. Restore the monitor's supported refresh rate and resolution through Settings > System > Display > Advanced display. A cable or monitor fault will not be fixed by repeatedly reinstalling Windows drivers.
Escalate persistent or pre-boot flickering
If flickering appears before Windows loads, persists in firmware screens, follows physical movement of a laptop lid, or affects only a damaged panel, seek hardware service. If it begins only after sign-in and neither Microsoft path isolates it, record the driver version, app changes, display model, and Task Manager result for the PC or graphics vendor.
