HP monitor, no signal, no source, sleep

[luvlii]

My monitor is not catching the signal. It turns on fine when it’s plugged in. I tried resetting it, I rebooted, I opened the tower to check for loose objects, I replaced my cords, I tried a new monitor and that didn’t work either. There are no beeping noises when I turn on my computer, and the monitor was working fine Thursday. I followed the HP support video on YouTube step by step btw.

I think there may have been a short in the cable, but it’s still turning the monitor on, so I’m not sure why it’s saying no signal. I tried using the cables from another computer and it still didn’t work!

Please help me
