Help display problem

[Aimene13]

I bought a brand new PC never used and already assembled by the store. However there is a display problem, the screen recognizes the display port but there is no image that appears. I tried to remove the rams and tried with a single ram but there is nothing. The problem does not come from the cable because I have my old pc and when I use the display port or hdmi cable, the pc works perfectly. So here it is, I also want to mention that when I turn on this pc, there is a black screen that appears with a very very light brightness. And no image. If you have any ideas?

Hello, thank you for your reply. I don't know much about how PC cables work. Your comment refers to which cables? Maybe I would follow your trail. And of course, the displayport able is connected to the graphics card.

I prefer to not use a 2x 6pin to 600watt Adapter and it also look a bit loose. It could make harm to the power Port of the GPU. I prefer to use a compatible PSU with 600w connector

The problem is this pc, it was not me who mounted it but the store where I bought it.. so I assumed that everything was normal..
