Ok so I just put together all my parts for my new build. However I do not get a beep when I plug my computer into a speaker and turn it on. I made sure the speakers worked by plugging them into my laptop. When I plug the video card into my tv via hdmi I get the message "please power down and connect the pcie power cables". I have plugged one cable in but my power supply that came with my case seems to only have one of the two pcie cables. When I plug the computer into my tv via the motherboard VGA nothing comes up at all on the screen. Also, even if the video card is not plugged in at all I still do not get the post beeping. Do I have two separate problems here? What do you guys suggest I do? My motherboard only has a 4 pin atx 12_V slot but my power supply has a 8 pin atx 12_V cable. I plugged the 8 pins that fit into the slot but still no post beeping. Please help me!
