hey guys, my computer just got built and im having a problem. The card shows a black screen when I connected it, hard drive is spinning and the fan on the GPU was spinning as well. I have already uninstalled my display drivers and VGA controllers. What am I doing wrong? I have also tried taking the battery out of my motherboard to reset CMOS but still no go. I know the card worked because yesterday i saw it working, before I reformatted my computer. Also, my BIOS is up to date, thanks.

What could the problem be? bad gpu? if so is there a way i can fix it ?

EDIT: ok so i found a method that boot my computer up with the video card. It successfully booted up to windows found new hardware then my computer froze and it restarted and it didnt detect the video again up the restart. Its leading to the fact that my GPU is broken,but is there a way to physically repair it ?

You need to either try that card in another computer or try a different graphics card in your computer.

A black screen is almost definitely indicating a graphics card which is dead. Replace if under warranty.

It's possible something else is the problem but you need to do the above first to prove if it's the video card.
