I don't know if the GPU is the problem because i tried to plug the Signal cable to the Graphics Card but it won't show anything, so I tried plugging in into the MotherBoard-'s GPU which is the Intel one, But after i plugged it in it displayed, I don't know though if i can Fix the GPU i don't have that much money left to buy another one, Is it possible to fix a GPU to a PC Technician?
