Yeah, but i placed 2 different pcie cord to power the gpu do i have to put the connection from only one cord?
 


its ok to plug 2 different cords. i suspect the graphics card is the culprit. can you please remove the graphics card and connect your monitor to onboard graphics and see if it works.

 


Simply plug in the monitor onto the motherboard instead or the graphics card right?
