No but I dont even have a post that is displayed so I doubt that updating the windows driver would solve the issue.

@Bombastinator @Crunchy Dragon I agree it's a common mistake but sadly I did plug the power cable at the back of the GPU @SkilledRebuilds I also thought about that but couldn't find where to download the update

Hi, I have a desktop with : RAM: 12 GB of DDR3 RAM (8 + 4) GPU: GT 540 CPU: i3 2120 Motherboard: Foxconn 2ABF SSD (240 GB) HDD (1 TB) PSU: 450W PSU And this desktop works. I also have a spare RX 480 that I testes on another system and that I know is working. My issue is that when I try to change the GT 540 with the RX 480 nothing is displayed on the screen. I am building PCs since 2013 but here I'm at loss, I don't understand what's the issue then I thought about a PCIe lanes bottleneck. Could it be it ? If not what can it be ? Thanks in advanc master race
