I has problem with the Graphic and unable to install the newest Graphic Card Driver, Intel® HD Graphics 620.

It said something like : " The driver being installed is not validated for this Computer, please obtain the appropriate driver from the Computer manufacturer". I went to Computer manufacturer (Acer) but all the Drivers older than the one I have.

Download and save this driver:

https://downloadcenter.intel.com/download/29335?product=95443

Then, disconnect from the net.

In the device manager, uninstall the Intel graphics driver, checking the box to delete the software.

Repeat the above step until you get to the Microsoft basic display adapter.

Then, install the driver you downloaded.

Then, reconnect to the net.

Now, you should know that you will lose any customizations Acer has made to the driver you had installed.

Hi Al, It is a Acer laptop AspireE 15, E5-575T-58WH. Sometimes the Screen flickering but It does not freeze as before, Thanks.

You should be using the drivers from Acer for their laptop.

I would download and install the audio driver.

Hi Al, I installed the Audio driver, I had another Parameter service problem

[AlHill]

The only thing I can recommend at this point is that you remove the graphics driver (7755) that you installed earlier, and use only the graphics and sound driver provided by Acer. Those were tested by Acer. If you still have problems, Acer will need to support their laptop with the drivers they supplied.
