45L turns on but wont display

[sam45L]

I started my computer and it is lighting up fine and looks good but it will not display. Omen 45L Gaming PC I purchased last september. 

I have already unplugged displays turned them off and replugged them in. That didnt fix it.

Usually the keyboard I have plugged in will go to sleep after a while and it is not going to sleep.

Hi @sam45L 

Welcome to the HP Forum.

I guess the PC is out of warranty if purchased in September, 2022.

You power on the PC, fans spin, and you have RGB effects but no video out to the monitors. For the time being I would use one monitor to simplify troubleshooting. 

The keyboard not sleeping could  suggest Windows is not running.

It looks like you may have a hardware problem. Finding the system fault is a process of elimination.

It could be a power delivery problem from the power supply to the MB and components connected to the MB and PC if the monitor and data cables and power cables from the graphics card to the monitor are okay.

Check power supply connections to the MB (24 pin and 4 +4 pin EPS). Check power supply connection to the graphics card.

I would disconnect all peripherals, only use one monitor, to check for a POST.

Disconnect internal storage drives.

Then try onboard graphics if the CPU and the MB support this. 

Remove the RAM. See if you get a "no RAM" POST error when no ram is connected to the MB. Then try each stick of factory RAM, one at a time, in each memory slot if you get a "no RAM' error message at startup.

No change in behavior suggests the problem could be with the power supply, MB, or CPU. A faulty power button could cause weird stuff. Check the power button connection to the MB.
