I'm in the middle of building my first computer, and I have a television monitor, with a simple HDMI cord installed. It's the external build (only psu [Seasonic X750W], gpu [EVGA GTX 670 reference], ram [Corsair Vengeance 2X4GB], cpu [i7-3770k], and cpu cooler [Corsair H60].
Nothing is appearing on my screen, and my television just says "No Signal". Everything turns on in the computer, and I only get the error code for "A2" which means there isn't an HDD. This is my external build, and I don't know if it's because I'm using HDMI to connect the build to the television. I need help, because I'm worried if I just spent $1400 for nothing.
If your TV can use VGA try that first, also, try a spare hard drive if you have one lying around, if that doesn't work then RMA the motherboard (you will probably only have to pay shipping and handling)
