GPU must not be connected to your monitor? Or a corrupt windows install.

Is the monitor plugged into the 1080 or your mobo?

Did you plug PCIe power into the gpu?

Did you set your bios to use PCIe graphics instead of iGPU?

As i said it is connected to the monitor as it showed the windows logo and the windows install is fine, was working with the old gpu just 15 minutes ago

If you see the Windows logo but then screen turns black it's definitely a software related issue. It might be a driver conflict. If you have a driver installed for the iGPU try uninstalling it then try the GPU again. The OS might be loading the iGPU driver and it's conflicting with the GPU.

so will it be safe to turn off the computer then?

If the display is black and not responding it shouldn't hurt anything to hit the reset button to regain control of the system.

Are you using anything like MSI Afterburner? If you are it could possibly be tweaking the GPU's clock settings.

You didn't say this was an x79 system. I assumed the platform had a iGPU or the motherboard had it's own graphics processor.

Computers can act finicky sometimes when installing new GPU's it might have been all it was. Let the forum know if this black screen comes back again.
