Hi. i've been trying for months but every time i download a graphics driver from here it said's not supported. and when i try to auto search updates for anything in Device Manager it searches none stop and i have to ctr alt delete to end it. So i followed the support on how to find the driver version i have and i attached a screen shot here. i think i might need to update the processor driver first before it supports graphics driver updates, but i don't know how.
Unfortunately, your B820 (Sandy Bridge) processor and HD Graphics are not supported on WIndows 10:
Thus, there is no driver except for the Microsoft generic driver.
