Apu and dedicated graphic card. Black screen

[maurice.marvin8812]

My problem is i cant change primary display adapter to pcie. Whenever i changed it, and graphic card installed. My pc will boot a couple of second then shutdown. But when i use my primary display adapter onboard. My pc just boot perfectly.

The problem is when i use primary display adapter onboard my pc will boot but my dedicated gpu cant show any display, its just blank. And also my pc recognize my dedicated gpu, but cant show display.

I try to plug my gpu to my friends rig and its work perfectly.

My spec :
A10 7890k
Asrock fm2a58m-vg3+ r2.0
Galax exoc 1050ti
Team elite 2x4 gb 1600
Wd blue 1tb
Dvd rw
Corsair cxm 650watt
6 case fan 120mm

I just bought the psu, so it wont be any trouble. I already check my memory ram with windows memory diagonistic and got 0 error.

Any solution ??

And also i tried my friends gpu once (which is 750ti) and it wont boot when my primary display adapter is pcie.

Have you plugged the display cable directly to the graphics card (when installed) instead of the motherboard?

"Ijust bought the psu, so it wont be any trouble."

Well it sounds to me like it's not providing enough power (insufficient amps probably) with the 1050Ti (or your friend's 750Ti) installed, hence the boot problem.

Yes i already plug my hdmi cable but its show black display. While my vga adapter i plugin on motherboard show display but its said display 2.

The system can run if i select the primary display adapter onboard. The gpu running aswell, i can even install the driver and my device manager recognize it. It mean my psu capable for my system isnt?
