Macpro 5,1 would not boot

Hi, I recently faced this issue where my Mac Pro would not boot. I tried nvram reset and it did not boot, I do not see anything on the display. I’d appreciate if anyone has faced this and can share what fixed it? In addition, if I power it off and turn it on, I still hear a chime and without holding any key on the keyboard. Still nothing on the screen. Did I mess my system up! :/

Edit: if I remove my usb installer, and turn it on, it chimes, nothing shows up on screen and eventually turns off.
