Computer booted when GPU was not connected but won't show anything on screen whe
So I successfully booted my computer when I had my CPU and RAM on my motherboard. Now that I have added my GPU, my monitor doesn't display anything on screen when I turn on my PC. My CPU cooler fans turn on, so I'm assuming that the mobo didn't break during the GPU installation process.
I have an Asus Maximus IV Gene-Z, an i5-2500k, and a EVGA GTX 570. I'm plugging the PC into my LED TV via HDMI cables. I tried plugging the HDMI cable to both the mobo and the GPU with no luck.
