Black screened monitors unresponsive

[Tylermont1]

This morning when I turned my computer on the desktop was running and I could hear the fans running, but my screen wasn't showing anything. I turned it off did a quick dust and it worked. I just got home and the same thing happened, but this time I did a full dust clean and it did not work. I've tried using different monitors that I know work and it doesn't work. The ports show no damage and I've also reset the cmos any it hasn't seemed to work. Currently I can still boot it up and see that the monitors turn on and then go to power saving mode (new cords didn't fix it either) my mouse doesn't light up on the bottom.
If anyone could help me out I'd greatly appreciate it

Any help?

Greetings @Tylermont1,

Thanks for the post and Welcome to HP Forums. 

I understand that you are not getting any display on any monitors but are able to hear the computer boot. Don't worry, I will be glad to help. 

Kudos to you trying to troubleshoot the issue on your own.

You have mentioned that you have checked the power saving settings, may I know how were you able to check the power saving settings with any display?

Was there any BIOS update installed before this issue started?

Have you tried using both VGA and DVI ports to check if you are able to get any display?

Recommend you to try rolling back the BIOS while holding down Win + B during startup. (If possible, please use a USB keyboard connected to the rear of the computer) 

Please refer to this HP Article for assistance in rolling back the BIOS.

If the issue persists, you might need to replace the graphics card on the computer.

Is there a port where I can install a graphics card on my computer? I read around that says this computer has a built in graphics card that is in the motherboard. The key combination to reset BIOS did not work. I use two monitors when I play and I've switched them around seeing if they would work. It says no signal from computer on my monitor. I've also tried a third newer monitor.
