The 0x00000003 or INVALID_AFFINITY_SET error occurs when there’s an issue with hardware compatibility. It’s usually seen after the installation of incompatible equipment.

How to fix:

  1. Identify the Incompatible Hardware: Check the hardware that was installed right before the error message appeared. It could be the culprit causing this problem.
  2. Replace the Hardware: If you identified the incompatible hardware, replace it with one that is compatible with your Windows system. Make sure the new hardware’s drivers are up to date.
  3. Update Drivers: If you can’t identify any newly installed hardware, then the error might be due to outdated drivers. Update all your hardware drivers, especially those related to the motherboard and graphics card.
  4. Perform a System Restore: If the error still persists after replacing the hardware or updating drivers, you can perform a system restore to roll back your system settings to a previous state when everything was working fine.
  5. Contact Support: If you’ve tried all these steps and the error still persists, it would be best to contact Microsoft Support or your hardware manufacturer’s customer service for more assistance.

Remember to always back up your data before making any significant changes to your system to avoid data loss.
