[SOLVED] GPU fan is On, but No display

[suamed]

Hello, i have core i3 3240, 8 gb ram ddr3 665mhz, ECS H61H2-M12 Mobo, and HIS r7 240 gpu.
Okay, Problem is, i plugged in my r7 240 and it got no display, but the fan is on. im using the vga cable, then change it to dvi-d but still no display. but, when i plugged the vga cable to the mobo, while the gpu is still intact with fan spinning, there is display but the gpu, as you expected. not detected.
Then maybe i thought my pcie is faulty, and i change it to an older gpu which is 9600 gt and voila it works just fine. no problem at all.
I never tried the r7 240 on other pc currently but it used to work fine on other pc that i got back then. i got the feeling that its still works just fine. and i really don't want to buy a new one right now. any help?

You're advised to try the discrete GPU on a donor system with ample power for the entire system to rule out a dead or dying GPU.
