Hi Please Help. I bought a new EVGA 450BT and installed it to my Home Desktop because im doing a little project and turn it into a gaming desktop. My Desktop is Dell Inspiron 3847. I carefully connected all Wires into my motherboard which is 24pin, 4pin, hard drive, optical drive. But there is still no signal to my monitor. I cleared the cmos but nothing happened. I checked if all wires are correctly attached but nothing happened. I reattached my old psu and everything was fine, so its not my vga/hdmi wires or my monitor. Please Help
