Hi, I am an independent advisor and welcome to Microsoft Q&A.
Let me help you with this issue.
I understand you are getting a green screen on your computer.
Have you tried a hard reset?
Is this for a laptop or a desktop?
Turn it off completely by pressing and holding the power button until it completely goes off.
Unplug the power adapter.
Remove the battery (if removable).
Hold the power button for 15–30 seconds.
Reconnect the battery and power, then turn it back on.
If the battery is built-in, just hold the power button for 15–30 seconds until it shuts down, then restart.
If it keeps showing the green screen boot to Safe Mode.
Power off the laptop.
Power on and repeatedly press F8 (or Shift + F8 / Shift + F11 depending on model).
Choose Advanced Startup Options → Troubleshoot → Startup Settings → Safe Mode.
Once in Safe Mode, go to Device Manager, expand Display Adapters.
Update the driver, or if this started after an update, roll back the driver.
