Checkered screen on G60

George, try to start it in safe mode, check the display with a lower resolution. Reinstall your video driver. Should that yield no change, open your laptop and check to make sure that all your cable, in particular the LVDS is properly seated. Install an external display and see if that shows the same pattern. If it does, and it is most likely, you are having a GPU failure. What that means is that you'r GPU shows solder fractures. This can only be repaired by either a reflow, which will be temporary, or by a more permanent reball of the GPU. Hope this helps, good luck. Hope this helps, good luck.
