Is my monitor suddenly going dark when I use a brand new graphics card (9070 XT) and processor (9800X3D)?

I would suspect the monitor power cable. Make sure that the cable is fully inserted into the monitor and of course into the wall receptacle as well. If the monitor/s are not momentarily losing power then we can start sussing out PC hardware. You have the display cable plugged into the graphics card and not the motherboard, right? If so try using the iGPU from the CPU by connecting the monitor to the motherboard. I don't really think this is a PC issue, but I would remove and then reinsert the graphics card followed by the CPU. Take a picture of the motherboard pins for the CPU and check for any bent pins. Make sure that all the cables to and from the PSU are fully seated. Try the same thing with the RAM. Make sure there are no loose screws or otherwise conductive parts touching any of the parts. A small shake when power is disconnected from the PSU can cause a metallic noise should there be anything doing this.
I share in that same bad luck. When I got my standing desk, things started getting worse too. Turns out that the wire from one of my monitors was getting pulled against the wall enough to make it flicker and shut down sometimes. We all learn by trying something new, and it's pretty cool when we find people who already messed up so we don't have to start over.
It happened all over again. I checked my cables and saw that my PC plug was a little loose in the wall socket. Could this be causing the problem? Probably not at all because unplugging would have just turned off my computer, but maybe it messed up the power going to the graphics card (GPU)?
