My new built desktop pc doesn't display anything on my screen. I connected a system speaker and it gave me 1 long and 2 short beeps wich means there is a video error. I removed my graphics card and tried to start my pc again but got the same error. Connected the graphics card again but still nothing. Is something wrong with my motherboard?

It does not.

I tried to place the graphics card in another pci slot, the beeping stopped but it still wont display anything. I've tried hdmi, vga and dvi cables but nothing works.

The pc does not have any trouble with booting up. When i don't have the GPU in and try to connect to the motherboard the screen still wont display anything.
 


Without a screen, you cannot know if the PC boots up properly.

Try resetting your BIOS still with no GPU and connected to motherboard. (you can reset it by removing the battery for a few minutes)
