I’m sorry you are having problems but let me help you.
Since your computer has the switchable graphics technology you should be able to choose what graphics resource to use or use both while using the system.
I would recommend you accessing the BIOS of the computer and disable the video card and enable the onboard graphics. It is important to mention that the option may be available depending on the Computer Manufacture since they sometimes block the options at the BIOS level.
In regards the issue you are having installing the driver, you can check some more steps at the following link:
thank you for your help , i checked the bios settings but there isn't much that i can do , no option to switch graphics , is it locked ? do i need to update the bios from acer or use a modded one ?
the thing is there's nothing that indicate i have intel hd graphics ( device manager , hardware monitoring tools )
the only thing that says i have one is cpu specs.
Computer Manufacture sometimes locks the BIOS options so this may be the reason why you don’t have the option on your laptop.
My best recommendation at this point is to contact the Computer Manufacture to confirm if there may be a problem with the unit and if so they can help you with a possible warranty.
