So i just build a new pc and when i turn it on the gpu starts spinnig the coolers and cooler but the monitor wont register a hdmi caqble and even when i plug in usb it wont work what do i do
If you have on board GPU have you tried that port to see if there's any output? Also have you re-seated the GPU? Fans spin based on power connection, has nothing to do with data transfer from the PCI-e slot. Are you using a straight through HDMI cable or an adapter on one end? Any beep code?
