Alright, so I originally had a 4060 8GB as my graphics card, and I wanted to update it to a RTX 7800 XT, so I put in that card and it was working perfectly fine with no issues, the next day it stopped showing display but it would show that it was attempting to make a connection to my monitor because my monitor would say that it was tryting to connect to display port everytime I would turn on my PC but it would show no signal. I tried updating the latest BIOS into my motherboard which I did and I tried uninstalling the NVIDIA Drivers that I had installed, It is not a CPU issue either because I run a I9 14900KS, but what I realized was the wattage on my PSU was 600 Watts so I recently installed a 850 Watts PSU which is well above the range you should run a 7800 at. I put it in today and did not work. Myy 4060 still works for display as I am using that right now. Keep this noted, my graphics card would turn on and the RGB would turn on to.

Ok, if you are not receiving a signal even in the BIOS, unfortunately it is not a problem related to Windows or the operating system, but rather a possible hardware conflict.
In this case, the best thing to do is to take the device to a technical support to check the cause of the conflict.
Have tested it on separate monitors and different cords on my computer
Have you checked that all the connections are correct?
Could you check if the same problem occurs using another monitor on your computer?
The card is not faulty, just tested on my friends computer and ran perfectly fine. I have no signal at all but it attempts to make a connection.
Hello my name is Jonathan, I'm here to help you with this problem.
With the RX 7800 XT, do you have video in the BIOS or do you have no signal at all ?
Try testing using another HDMI or Display Port, or another monitor/TV if possible.
If the problem persists, it could be a problem with the GPU itself and the best thing to do would be to contact the manufacturer's support or activate the warranty if you still have one.
