The red screen issue you're experiencing after resetting the graphics driver could be due to a few reasons:
- Graphics Driver Issues: The graphics driver may not be functioning correctly after the reset. You might want to try reinstalling the graphics driver or updating it to the latest version from the manufacturer's website.
- Display Settings: Sometimes, the display settings might change after a driver reset. Check your display settings to ensure they are configured correctly.
- Hardware Problems: There could be an issue with the monitor or the graphics card itself. If possible, try connecting to a different monitor or using a different graphics card to see if the issue persists.
- Corrupted User Profile: If the user profile is corrupted, it might lead to display issues. You can try creating a new user profile to see if the problem continues.
Since you mentioned that you cannot open Task Manager, it may be necessary to perform a clean boot to troubleshoot further. This can help identify if a startup application or service is causing the problem.
If the issue persists, you may need to seek further assistance or consider restoring your system to a previous state when it was functioning correctly.
