Always completely uninstall the current drivers before installing new ones. Use a driver uninstaller tool to make sure all remnants of the old drivers are removed. Ensure that you download the correct drivers for your specific operating system (Windows 7, 8, 10, or later). If you are uncertain about the driver version, it's wise to research the specific drivers before installation. If the card isn't detected, check the Device Manager in Windows to see if there are any error messages or conflicts. Conflicts with other hardware devices can sometimes lead to driver-related issues. Try updating the drivers directly from the device manager. If the problem persists, try a clean install of the drivers, avoiding any optional components like the Catalyst Control Center (if available). Always make sure your Windows operating system is up-to-date.
• Overheating: Although the ATI Radeon HD 6450 isn't known for generating a lot of heat, overheating can still occur, especially in poorly ventilated cases. Ensure the card's heatsink is clean and free of dust. Consider adding more case fans to improve airflow. If you are experiencing overheating, check the card's temperature using monitoring software such as MSI Afterburner. If the temperature is exceeding safe levels (around 80°C or higher), consider reapplying thermal paste to the GPU. Always ensure that the graphics card's fan is working properly. Clean or replace the fan if necessary. Poor case airflow is a common cause of overheating; make sure there is adequate ventilation. Avoid overclocking the card, as this will generate additional heat. Make sure that the fans in your computer are properly functioning to help with air circulation.
• Artifacting or Display Corruption: This means you're seeing strange glitches, lines, or colors on the screen. This could be a sign of a failing GPU or memory. Try underclocking the card using software like MSI Afterburner to see if it stabilizes. If the artifacts appear only in specific games or applications, the issue may be related to the software rather than the hardware. Test the graphics card with different games to determine if the artifacts persist across all applications. If artifacting is occurring, check your system memory for errors. Ensure that the drivers are correctly installed and that the card is compatible with your motherboard. Sometimes, the issue may be resolved by lowering the graphics settings in your games. This will reduce the load on the card and may prevent the artifacts from appearing. If the card is under warranty, consider contacting the manufacturer or retailer for a replacement.
