screen frozen when update the intel graphics driver

[TSky]

thinking about that the 6700K graphics driver has not been updated for a long time

so i tried to download the latest graphics driver to update~

On the installation period, the screen switch to my nvidia Graplic card, and then the computer freeze on the black screen....

In the moment, i think the new driver may be crash or something...

so, i tried to install the old driver, to test whether if this is computer's problem...

the old driver cannot work too!!!!!

WTF!!

I can install the old driver just a few months ago...

and my computer has no big change since the time from the success installation of old driver...

i cannot figure out what happen./..\

old driver: win64_154514.4590

new driver: win64_154516.4627

OK....

i got the method to fix this problem finally.....

JUST UNPLUG the HDMI Cable

of the other graphic card when installing the new version graphics driver of intel CPU

the reason may be the software setting or something that i don't know...so weird...............
