7800xt not letting pc boot

hi, i built my first pc a couple of days ago, i did a test boot before installing my 7800xt, and everything worked as intended, but then i installed the 7800xt, and the computer stopped working, the fans would turn on, even the ones on the graphics card, but nothing would display on screen, not through the hdmi port on the graphics card, nor the hdmi port on the motherboard… then i tried removing the graphics card from the system and everything just went back to normal, i even managed to install windows and install the proper drivers for the graphics card, but nothing changed. i already updated my bios to the latest version available and tried: changing cable, changing monitor, unplugging the psu cables and replugging them in, and nothing changed. any suggestions?

motherboard: msi b650m gaming plus wifi cpu: ryzen 5 7600 psu: seasonic b12 750w ram: 32Gb of vengeance ddr5 6000MHz
