Question Mobo shows green light after plugging new monitor in

[VeryGentleman1]

Hey, I got a new BENQ MOBIUZ EX2710Q monitor and plugged it in but had no display and through remote desktop had nothing boot anyway.
I unplugged my monitor and now it won't boot at all. At first it only showed an orange light but then I resorted, reseated reeverythinged my ram and had no change. Tried with just one, etc.
After one of my first times powering on my pc after doing this ram stuff, my lights now go from amber to red then white and finally staying on green.
My pc had no issues before this so I have no idea what I could do.

Any help is appreciated ty

Are you referring to the debug LED's on your motherboard? If so, due to the fact that there are a vast number of motherbaord's out there, not to mention the camps of processors, we will need to know the make and model of your motherboard.

Mentioning the specs to your build will also be of service to troubleshooting the problem. Please list your specs like so:

Did you hook it up to your discrete GPU(assuming you have one to work with) or your motherboard's display output ports?

Check all the connecting cable to the mother board are connected and the harddisk is running (Some time the hard disk may be dead).

Still nothing I've only reseated my ram and connected a new monitor and since then my entire pcs just died
