Issues with noisy or corrupted graphics in games like Call of Duty: Modern Warfare 2 can be frustrating and may be caused by a variety of factors, from software conflicts to outdated drivers or hardware problems. Here's a step-by-step guide to help you diagnose and resolve the issue: 1. **Update Your Graphics Drivers**: - This is often the most critical step. Graphics card manufacturers like NVIDIA, AMD, and Intel frequently release updates that can improve performance and fix existing bugs. - Go to your graphics card manufacturer's website and download the latest drivers for your card. 2. **Check for Game Updates**: - Make sure you have the latest patches for Call of Duty: Modern Warfare 2 installed, as these can fix known issues including graphical glitches. 3. **Lower the Graphics Settings**: - Try lowering the graphics settings in the game. Sometimes high settings can cause stress on your GPU, leading to noisy or corrupted graphics. - Turn off or lower settings such as anti-aliasing, shadow quality, and texture resolutions to see if the issue resolves. 4. **Verify the Integrity of Game Files**: - If you're playing on platforms like Steam or Battle.net, use the built-in feature to verify the integrity of game files. Corrupted or missing files can lead to graphical issues. 5. **Overheating and Hardware Stress**: - Ensure that your PC is not overheating. Check the temperatures of your CPU and GPU with software tools like HWMonitor or SpeedFan. - Keep your PC case clean and ensure proper ventilation. 6. **Power Supply**: - Sometimes a failing power supply unit (PSU) can't provide the necessary power to the GPU, resulting in noisy or corrupted graphics. - Make sure your PSU is of a high enough wattage to support all of the components in your system. 7. **Monitor Refresh Rate and Resolution**: - Ensure that your monitor’s refresh rate and resolution settings in Windows are set to the native specifications of the monitor. 8. **Reinstall the Game**: - As a last resort, uninstall and reinstall Call of Duty: Modern Warfare 2. This can resolve the issue if it's related to the game's installation. 9. **Try the GPU in Another PC**: - If possible, try your graphics card in another PC to see if the issue persists. This can help you determine if the issue lies with the card itself. 10. **Hardware Diagnostic**: - If none of the above steps work, there might be an issue with your GPU or other hardware components. Running a hardware diagnostic or reaching out to a professional for a checkup could be necessary. When attempting these troubleshooting steps, take each one slowly and monitor your game for improvements or changes after each step. If the problem persists through all of these steps, consult with the game developer's support team or take your PC to a professional to ensure there isn't a deeper hardware issue at play.
