Hello,
It's possible that the issue you're experiencing during raiding and M+ gameplay in World of Warcraft could be related to outdated or faulty drivers for your graphics card or other system components. Here are some steps you can take to troubleshoot the issue:
Update your graphics card drivers: Go to the website of your graphics card manufacturer and download and install the latest drivers for your card.
Check for Windows updates: Sometimes, outdated Windows versions can cause issues with graphics cards. Make sure your system is up to date with the latest updates from Microsoft.
Check your system for overheating: Overheating can cause your system to freeze or display a blared color screen. Make sure that your system is properly cooled and that your fans are working correctly.
Check your system for any hardware issues: If you continue to experience issues after trying the above steps, it's possible that there could be an issue with your hardware. Consider bringing your system to a professional technician for a diagnostic test.
I hope these steps help you resolve the issue. Let me know if you have any further questions or concerns.
