When using Windows, you may sometimes encounter a graphics card error code 43 in the Device Manager. This usually indicates an issue with the graphics card or its driver, preventing the system from recognizing or using the card correctly. Here are some methods to resolve this problem:

1. Restart Your Computer

Occasionally, error code 43 can result from a temporary system glitch or resource conflict. The simplest solution is to restart your computer. A restart can refresh the system, and this may resolve the error, especially after installing new drivers or updating the system.

Driver issues are one of the main causes of error code 43. To fix the problem, try updating the graphics card driver.

3. Check the Physical Connection of the Graphics Card

Sometimes, error code 43 may be caused by an improperly installed graphics card or a loose connection. You can open the computer case and make sure the card is correctly seated in the motherboard's PCI-E slot, and that all power cables are securely connected. If possible, remove the card and reseat it to ensure a proper connection.

4. Update Your System or BIOS

In some cases, error code 43 can result from incompatibility between the Windows system or the motherboard's BIOS and the graphics card.

- Update Windows: Go to "Settings", open "Windows Update", and click "Check for Updates" to ensure your system is up to date with the latest patches.
