Graphics Cards

Hello,

Apple iMac 2019 with Boot Camp and Windows 10 Build 2004 showed several Bluescreens these days.

The latest one from : "SYSTEM THREAD EXCEPTION NOT HANDLED What failed: atikmdag.sys"

They can happen e.g. if I open Mozilla Firefox.

Since February 2020 and October 2020 I had no Bluescreens.

See if the latest one works without BSODing your Mac even though it seems to be older than the one you have now installed.
