Gpu/Mobo problems

[frippe44]

So when I insert my new graphics card into the pci slot and boot up I just get black screen all the fans are spinning,but when I run on integrated graphics it boots fine, I have tried several gpus in my system non work. What could be wrong?

Have you plugged in the PCIe power into the GPUs?

Yes.

Have you plugged in the PCIe power into the GPUs?

It could be that the GPU isn't getting enough power, I just had to send in a defect PSU because of this problem.

[frippe44]

How can I be sure?

You have another power supply around? If so you can try to use that instead and see if that boots up, that's how I knew it was my PSU that was defected.

Maybe the system still tries to output the video signal via the integrated GPU? Try to deactivate the onboard GPU in the BIOS and set the card in PCI Slot X to be the main output one (at least with gigabyte boards this is possible, will be similar with other manufacturers).

Cant find that setting .

In my bios it's named "initial video output", look for something similar.

Also if you boot using integrated graphics can you see the dedicated GPU in the device manager?

If I put my graphics card in the screen wont notice anything it stays black, and in the bios i can change pci gen x to 1 2 3
