To fix screen artifacts on a laptop, we must first diagnose the underlying issue. This process involves checking for both software and hardware problems.

Software Issues

Software issues often cause screen artifacts. First, update the graphics driver by going to the device manager, selecting the display adapter, and clicking “Update driver.” If the issue persists, try rolling back the driver to a previous version. Restart the laptop after making changes.

Next, check for software conflicts. Uninstall any recently installed applications that might interfere with the graphics system. Use safe mode to identify if third-party software causes the artifacts. If safe mode resolves the issue, a recently installed software is likely the culprit.

Lastly, perform a malware scan. Malicious software can corrupt system files causing display issues. Use a trusted antivirus program to scan and remove any threats. Update the operating system to the latest version to ensure compatibility and security fixes.

Hardware Failures

Hardware failures can also cause screen artifacts. Start by inspecting the laptop screen for physical damage. Cracks or other visible damage suggest a need for screen replacement.

Next, check the internal connections. Loose or damaged cables connecting the display to the motherboard can create artifacts. Carefully open the laptop using appropriate tools, secure the connections, and reassemble the device.

Overheating often leads to screen artifacts. Clean the cooling fans and vents to ensure proper airflow. Apply new thermal paste to the CPU and GPU if necessary.

Finally, inspect the graphics card. Integrated GPUs rarely fail, but dedicated graphics cards can malfunction. Test the laptop with an external monitor. If artifacts appear on both screens, the graphics card might be faulty. Consult a professional for further diagnostics or replacement.

Fixing Software-Related Screen Artifacts

Updating software can resolve laptop screen artifacts stemming from software issues. We’ll cover key strategies, including updating graphics drivers, adjusting display settings, and running virus scans.

Updating The Graphics Driver

Updating the graphics driver often resolves screen artifacts. Visit the manufacturer’s website to find the latest driver. Use the “Device Manager” in Windows to uninstall the old driver before installing the new one. Restart the laptop after installation to ensure the changes take effect.

Adjusting Display Settings

Adjusting display settings can minimize screen artifacts. Open “Display Settings” in Windows and set the recommended resolution and refresh rate. If artifacts persist, try different resolutions and refresh rates to find a stable setting.

Running A Virus Scan

Running a virus scan detects malware that may cause screen artifacts. Use reputable antivirus software like Norton or McAfee. Perform a full system scan and remove any detected threats. Restart the laptop post-scan to confirm if the artifacts disappear.

Fixing Hardware-Related Screen Artifacts

Screen artifacts often stem from hardware issues. Let’s explore some essential steps to address hardware-related screen artifacts.
