    Hello, and welcome to Apple Support Communities!



    Can you remove the graphics card entirely and attempt to power the computer on?

    I'm also having this issue. I re seated the ram, HDD, and graphics card. I think maybe the PSU is dead? I don't have much experience with this model however.
