So, basically my pc is 4 years old. I have i3 4160 , 4gb (ddr3) and internal graphics card is intel hd 4400 . So, I got an AMD RADEON R7 250 (ik gpu will bottleneck but I have no choice) .
The first time I installed the graphics card, through the graphics driver and the pc I found out the pc did detect the gpu but was not utilizing it at all. It was still using my internal graphics card (Intel hd 4400) .
So to forcefully make my pc use the Radeon r7 , I disabled my my Intel hd graphics driver and at that moment my monitor went full black even though the pc was running . So, I installed windows again in order to make my pc run .
Now everytime I install the GPU , monitor is black even though the pc is running . But when I take the GPU out , pc and monitor works perfectly . I tried booting with Safe Boot and install my GPU but the results are same, monitor turns black after inserting GPU .
Can you guys help me out a bit ? I am not a pc master myself .
