Black screen after Windows starts
The display goes black when entering Windows or after sign-in. If there was never a boot image or any sign of Windows, start with PC turns on but no display.

See all the clues. Choose the one that matches what you observe.
There is a cursor or Ctrl + Alt + Delete responds
Look for a visible way to inspect Explorer without blindly closing tasks.
Monitor, dock or projection changed
Compare the active output before changing the driver.
No Windows screen returns
Use a safe recovery entry; do not create shutdown loops.
It began after a graphics-driver update
With usable video, driver rollback can be a targeted test.
Safe Mode works but normal startup does not
Compare what normal startup loads without declaring all hardware healthy.
Diagnostic signals
- ObservationThe security screen is visible
- There is a graphical path to inspect the session. It does not prove driver health, but avoids starting with reinstallation.
- ObservationOne monitor shows Windows and another does not
- The system produces video through one path: prioritize the other display, cable, mode and connection.
Step-by-step solutions
Try a graphics response without powering off
Observe whether Windows restores video or a security screen.
If Windows is not updating or undoing changes, press Windows + Ctrl + Shift + B once. A sound or flicker may accompany the graphics-driver reset. Wait for the response; sound without video does not prove the monitor is working.
If video returns, save work and note whether it began after a monitor or driver change to follow that branch. Otherwise try Ctrl + Alt + Delete once: a visible screen leads to session; no visible response leads to output/recovery. Do not repeat shortcuts indefinitely.
Inspect Explorer only from a visible window
From Ctrl + Alt + Delete open Task Manager; with a cursor you can also try Ctrl + Shift + Esc. If visible, find Windows Explorer and choose Restart. If absent, use Run new task and enter explorer.exe without elevation.
If the desktop returns, the session/Explorer was part of the failure; save work and inspect recent changes if it recurs rather than reinstalling the driver by default. If it does not return despite visible Task Manager, move to Safe Mode or an existing-account comparison; do not change registry Shell keys or delete the profile.
Isolate monitor, cable and projection
Check monitor power, selected input and video cable without changing several things. If another screen shows Windows, open Windows + P and choose a mode matching the display you will keep. Do not cycle modes or confirm options blindly.
If a known screen/cable or direct connection without a dock is available, compare while retaining access. Before removing a dock, close/eject storage and secure power and keyboard: it carries more than video. If direct works, check dock/cable compatibility; if internal works but external does not, focus on the external path.
If all remain black but Windows was visible earlier, follow recovery. If a known screen also shows no startup image, use the related no-picture guide; this is no longer just the Windows session.
Choose a safe recovery entry
If sign-in or the security screen is visible, save everything accessible and hold Shift while choosing Power > Restart. If Settings is visible, use System > Recovery > Advanced startup > Restart now; on Windows 10 it is under Update & Security > Recovery. This opens Windows RE, the recovery environment.
If none of those paths is visible, use a manufacturer recovery option or an already prepared recovery drive according to its manual. Alternatively, official installation media can open Repair my PC/computer when booted: do not choose installation, partition deletion or reset. Creating that USB on another PC erases its contents; use an empty/backed-up drive and get help if unfamiliar with the process.
If recovery does not appear, you lack a requested key or cannot identify the safe option, stop and seek help with the last visible screen. Do not force repeated shutdowns or blind boot commands.
Use the Safe Mode difference to prioritize
If Safe Mode shows the desktop but normal startup does not, minimal configuration works. This points toward what changes at normal startup: full driver, services, startup apps or profile. It does not prove GPU, cable and all hardware healthy.
If it began after a graphics driver, follow rollback. If it coincides with a new startup app and the desktop is accessible, record its state and disable only that nonessential app in Task Manager > Startup apps; do not touch security or managed software. Restart normally once. If unchanged, restore its state.
If another owned/authorized account exists, compare sign-in without creating or deleting profiles. If that account works, the affected session warrants review; do not copy or delete profile folders as a test. If Safe Mode also fails or a targeted change adds no improvement, give the comparison to support before deeper recovery.
Advanced checks
Continue if the earlier steps did not help. Read each procedure’s precautions first.
Enter Safe Mode for one comparison
From Windows RE choose Troubleshoot > Advanced options > Startup Settings > Restart. When the list appears, choose 4/F4 to Enable Safe Mode. Use the account password: PIN and biometrics are unavailable. Networking is unnecessary to observe whether the desktop appears.
If Startup Settings is absent in the environment you opened, do not substitute bcdedit commands: ask the manufacturer/IT for the appropriate path. If it starts, record cursor/desktop/external display and follow Safe Mode interpretation. Restarting normally exits this one-time selection.
Roll back the driver only when the change justifies it
With usable normal or Safe Mode video, open Device Manager > Display adapters > affected adapter Properties > Driver. If the problem began after updating it and Roll Back Driver is available, follow the wizard.
If rollback is unavailable, work with OEM/graphics support on a compatible version for the exact model and Windows. Do not uninstall both adapters on a hybrid laptop or the only one providing video. After a targeted change, restart normally and compare the same screen. If unchanged, preserve versions/results and stop the chain of changes.
Still not working?
Provide the last visible screen, Ctrl + Alt + Delete response, Explorer result, alternate monitor and Safe Mode, alongside the recent change. If the next step requires System Restore or installation repair, agree backup and effects with support; do not delete the profile or reinstall for an undiagnosed black screen.
