Question Graphics were working after PC rework

[Billm_in_Texas]

I recently upgraded my system and put my old motherboard, processor, and graphics into my wife's case. It is an upgrade for her. I stripped many programs that she would never use off and my 10s of 1000s of photos and the machine was performing very well. Today, I got a mess on the screen when booting up. I had initially put her graphics card on the machine but changed it to the one I was using. That is when a grainy-looking, multiple-imaged start screen is shown. It shows the Gigabyte startup screen then the Windows icon with the rotating dots then nothing. I have tried both graphics cards and the same thing happens. I have gone into the monitor menu and it shows hdmi with a circled exclamation point. Any thoughts on why this is happening? Thanks.

A couple of screenshots when starting up. This would indicate a good monitor and connection, wouldn't it?

Does anyone have thoughts on this? I'm wondering if it has to do with Windows drivers.

No one can help? I'm going to attempt a repair with the Windows disk.

It still went black when trying to boot from the Windows 10 disk. If the graphics card was bad, the above screens wouldn't show either, correct?
