Hi again,
Another information.. maybe it is obvious, but
If I disable Amd card on display adapters.. and try to enable intel hd 4000... no black screen
so reboot
And pc turns on normally.. on display adapters i can see; amd disable (disable before reboot) and Intel HD 4000 operating correctly (no code 43)
But if enable amd card.. black screen...and intel card code 43 after reboot.
This dxdiag is when Intel 4000 operating correctly after reboot and amd card has been disable.
tanks for follow these issues
