Hello, I recently bought the components for a PC that I finished assembling today. The PC powers on, everything seems to be working. So I decided to connect it to the monitor to install Windows, but a problem arises. I tried using DVI and HDMI cables and the monitor indicates "No Signal." However, earlier in the day, I used the same monitor on the same ports, but when I connect my PC, the monitor says "No Signal." Could I please get some help?
Thank you.

    First of all, you need to analyze whether the issue comes from the screen or the PC.
    When you start up, does the PC make noise, do the fans start up properly?
    Do you have a second screen easily accessible that would allow you to quickly check if the problem comes from the screen or the PC?

      First of all, thank you for your reply. Then, I think the problem comes from the PC. What I don't understand is that I used the screen beforehand with other devices, so the screen works as well as the HDMI port, and the DVI cable from the PC is connected to the graphics card, which does activate. Could the problem come from the ports of the graphics card?

      This is indeed the second point to analyze. If you are sure that the screen has worked before (and still works), then you should try connecting it differently to the computer using either DVI, VGA, or HDMI, depending on the cables and/or adapters you have on hand.

        I tried several things:
        DVI connected to the PC ---> HDMI connected to the screen and vice versa
        HDMI connected to the PC and the screen.
        The only ones I don't have on hand are:
        DVI on both ends and VGA.
        I will still try to get them.
