Keys to the Problem Checkerboard pattern covers portions or all of display
Welcome to Microsoft Answers.
I would suggest you to check for GPU.
GPU stands for graphics processing unit.
It's the main chip on your video card which does the actual drawing.
GPU artifacts can look like just about anything and can get sufficiently severe that
nothing on the screen is recognizable.
A common form of serious GPU artifact is a checkerboard pattern which covers the entire screen.
GPU artifacts are usually heat related and can often be solved by reducing the GPU temperature.
If your video card has a
fan then its main job is to cool your GPU.
You should check to make sure that it's spinning.
You can also try running the computer with the case open and aiming a desk fan at the video card.
If the issue still persists I would suggest you to check for the video card drivers that is, display adapter installed.
Uninstall and reinstall the latest drivers and then check -
Do check if any exclamation or cross marks are with the Display adapter in device manager.
If you have any of these marks then you will have to check for the adapter.
Click Start, and then click Control Panel.
Click System and Maintenance, click System, and then click
Note If Control Panel is in Classic View, double-click System, and then click
If you are prompted for an administrator password or for a confirmation, type the password, or click
In Display Adapter, expand Display Adapter and check with the adapter/drivers installed.
Right-click the display devices, and then click
When you are prompted to confirm that you want to remove the device, click
Restart the computer.
If you have still have issues with the drivers you will have to download and install the latest drivers from the system manufacturer website and then check.
Hope this helps.
