How to fix error error-no-signal-sent in Windows 11

Solution Steps

1. 1 Press Ctrl + Shift + Esc to open Task Manager. Look for any programs that are 'Not responding' under the Processes tab. If you find any, right-click and select 'End task'. This clears out stuck processes that might be blocking signal delivery.
2. 2 Press Windows key + R, type 'services.msc' and press Enter. Find 'Remote Procedure Call (RPC)' and 'DCOM Server Process Launcher'. Right-click each and select 'Restart'. These services handle communication between programs and hardware; restarting them can fix signal delivery issues.
3. 3 Press Windows key + X and select 'Device Manager'. Expand categories like 'Display adapters', 'Network adapters', and 'Universal Serial Bus controllers'. Right-click each device and select 'Update driver'. Choose 'Search automatically for drivers'. Outdated or corrupt drivers can prevent signals from being sent correctly.
4. 4 Press Windows key + R, type 'cmd', then press Ctrl + Shift + Enter to run Command Prompt as administrator. Type 'sfc /scannow' and press Enter. This scans and repairs corrupted system files that might be causing the error. Wait for it to finish (it may take 15-20 minutes).
5. 5 If the error persists, run DISM: In the same Command Prompt, type 'DISM /Online /Cleanup-Image /RestoreHealth' and press Enter. This fixes the Windows system image itself. After it completes, restart your PC.
