    Are you able to force your laptop into the recovery environment to perform a system restore to a date/time before you made the change?

    Start your PC, just as Windows attempts to load (spinning dots), press and hold Power Button for 5 - 10 seconds to perform a Hard Shut Down

    Do this twice

    On the third start Windows will boot into the Recovery Environment and from there you can access System Repair, Safe Mode, Command Prompt... etc.

    Go to Troubleshoot - Advanced Option - System Restore

    Check to see if you have a restore point you can go back to

    Changing the refresh rate to an unsupported value can cause a black screen because Windows keeps trying to use that invalid display mode. Use these steps to restore a working display mode.

    1. Try the built‑in display reset shortcut
      • With the laptop powered on and at the black screen, press Windows logo key + Ctrl + Shift + B.
      • This resets the graphics driver and can bring the display back if it’s just stuck on a bad mode.
    2. Cycle display modes
      • Press Windows logo key + P once, then press P again and then Enter.
      • Repeat this sequence a few times (Windows + P, P, Enter) to switch between display modes (PC screen only, Duplicate, Extend). This can restore output to the internal panel if it’s trying to send video to a non‑existent external display.
    3. Use Ctrl + Alt + Del to restart Explorer
      • Press Ctrl + Alt + Del.
      • If the security screen appears, select Task Manager.
      • In Task Manager, find Windows Explorer, right‑click it, and select Restart.
      • If Windows Explorer is not listed, go to File > Run new task, type explorer.exe, and press Enter.
    4. Force a full restart
      • Hold the power button for about 20 seconds to fully power off.
      • Turn the laptop back on and check if the display returns.
    5. If the screen is still black, use advanced recovery to change display settings Since Safe Mode still shows a black screen, use Windows Recovery Environment (WinRE) to roll back the change indirectly:
      1. Turn the laptop on, then hold the power button to force it off as soon as Windows starts loading.
      2. Repeat this 2–3 times until Automatic Repair / Recovery appears.
      3. Go to Troubleshoot > Advanced options > Startup Settings > Restart.
      4. After restart, press F5 for Safe Mode with Networking.
      5. Once in Safe Mode (if the display works there):
        • Open Device Manager.
        • Expand Display adapters, right‑click the GPU, and choose Update driver or Roll back driver if the issue started after a driver change.
        • Also right‑click the desktop, open Display settings > Advanced display, and set the refresh rate back to a standard supported value (typically 60 Hz).
    6. If Safe Mode still shows a black screen
      • In WinRE, go to Troubleshoot > Advanced options > System Restore.
      • Choose a restore point from before the refresh‑rate change or any recent display/driver changes.

    If none of these steps restore the display, the overclock may have exposed or caused a hardware issue with the panel or GPU, and professional hardware diagnostics would be required.
