Windows Code 43 Graphics Driver Error: Complete Fix Guide
If a GPU shows Code 43 in Device Manager, the problem is usually a corrupted or incompatible graphics driver, though overheating, loose seating, weak power delivery, or failing hardware can cause the same error, so the best approach is to restart, reinstall or clean-remove the GPU driver, then check cooling, power, and hardware stability if the error remains.
