Restarting after a DDU issue displays a black screen

[ahaks]

Hello, I just joined. I used DDU to try to fix a flickering problem I was having with a two monitor setup the other day. Sadly, the flashing persists, and my computer can no longer restart without becoming trapped on a dark screen. However, everything appears to be okay if I turn the computer off and back on.

My RTX 4070S's NVIDIA drivers were removed via DDU, however the device manager also shows that AMD integrated graphics are disabled. Since everything else appears to be working OK, I suppose I'd like to know why the Nvidia display adapter can't withstand a restart and how to resolve it.

Regards,

That's probably related to the problem you had at first with the flickering screen.
I don't know if you use HDMI or display port but first thing I would do I switch to another cable.
If same issue with another cable, I would try a CMOS reset.
I guess you have reinstalled the driver after removing it with DDU.

I think DDU has removed NVIDIA driver or conflict between NVIDIA and integrated AMD graphics card.
