I've been researching on my laptop and told me several times that I have two installed Chipset, I have seen that one of the two does not work and I think that is the last I installed when I upgraded drivers and controllers.
How I can unistall the second Chipset? would greatly appreciate your help
You don't have installed 2 chipsets, but obviously you have installed the driver package for your on-board Intel graphics adapter 2 times with different DeviceIDs (DEV_27A2 and DEV_27A6, one of them may be wrong).
You should be able to uninstall the wrong "Graphics Adapter" from within the Device Manager.
Usually the Device Manager will show the "wrong" or not properly working device with a yellow mark.
Please post a screenshot of the Device Manager after having opened the section "Graphics Adapters" resp. "Graphic Cards".
