Hp all in one 24 - k0034

I bought a used all in one 24 (k-0034). I wanted to use it to surf the internet or as a business computer but it's currently stuck in HDMI mode. When I press the power button it makes a lot of beeping noises and the screen stays black (a message does pop up *check HDMI or video source*). I just want to know how am I supposed to change the screens. Its quite annoying. And the keyboard does not work while it's like this nor does the mouse. Please help
