The two-second reset: Win+Ctrl+Shift+B
The shortcut asks Windows to tear down and reload the entire display stack — the graphics kernel, the driver and the compositor — without touching your session. Apps stay open, unsaved work stays where it is, and only windows on a multi-monitor setup may briefly rearrange. The beep you hear is the device reconnect sound, not an error.
It is the first thing to try, because it costs nothing and fixes the most common glitches. Among them: a frozen cursor with a responsive system, black screen after waking from sleep, an external monitor the system refuses to see, or artifacts after a driver hiccup. If the symptom survives the shortcut, move on to a deeper reset.
- Black or frozen picture while the PC still responds to Win or Ctrl+Alt+Del.
- External monitor not detected after docking or after wake.
- Artifacts, wrong colors or a corrupted picture after a GPU driver crash.
- Cursor stutter while audio and apps keep running smoothly.
- A stuck resolution or refresh rate after a game crashed to desktop.
A deeper reset through Device Manager
Right-click Start, open Device Manager and expand Display adapters. Double-click your GPU, open the Driver tab and try Roll Back Driver first — it is enabled only when Windows has a previous version stored, and it is the gentlest way back after a bad update. If there is nothing to roll back to, return to the device list, right-click the GPU and choose Uninstall device; on Windows 11 that dialog offers a checkbox that also removes the driver package.
Restart the PC either way. Without the package deletion, Windows reinstalls the same driver; with it, the system falls back to the Microsoft Basic Display Adapter until Windows Update or your vendor's installer supplies a new one. That is why you should download the driver from NVIDIA, AMD or Intel before deleting anything on purpose.
When a reset is not enough
If glitches return within hours, the driver stack itself is probably contaminated, and the next step is a clean install with Display Driver Uninstaller in Safe Mode rather than another on-top reinstall. Random black screens that survive all of this point elsewhere: a failing cable or adapter, overheating, an unstable overclock or the PSU under load. Test methodically instead of reinstalling the same driver a third time.
Keep an eye on temperatures with the vendor's tool while gaming. If you suspect hardware, test the card in another system before spending money. As a maintenance habit, Kleaner PRO users pair driver resets with its DirectX shader cache cleanup, since a corrupt shader cache keeps producing artifacts even after the driver itself is fine.
Questions and Answers
Does Win+Ctrl+Shift+B close my games and apps?
No. It reloads only the display driver stack; everything stays open. Windows may play a beep and briefly rearrange windows on a multi-monitor setup.
How do I reinstall my GPU driver after uninstalling it?
Restart first — Windows usually reinstalls a basic driver on its own. Then install the latest package from NVIDIA, AMD or Intel, or let Windows Update fetch one.
Why did my screen go black and come back with a beep?
Most likely you pressed Win+Ctrl+Shift+B, the graphics driver restart shortcut, or the driver crashed and Windows recovered it. If it happens rarely, there is nothing to fix.
