I just got done building my first Computer but I have encountered some problems. Whenever I turn on the computer the fans turn on and the lights also, however there is no display I tried to use VGA cables on the motherboard, DVI on the graphics card, and HDMI on both the graphics card and the motherboard. I looked up what was wrong with it on this site however most pointed to the PSU not being powerful enough or not plugged in and I have double checked myself by making sure that it was plugged in properly. I know the graphics card is working and has power going to it because the fan on the graphics card turns on. If it helps I have a Cooler Master Extreme power plus 500W PSU and a XFX R7770 core edition graphics card.

Any and all help is appreciated.

What is the connector type on the ASUS display, and it's input signal mode, AUTO/Analog/Digital? Does display show any message, like no signal, or something? Does the display have all three ports - D-sub (VGA), DVI, and HDMI?

The ASUS Monitor has VGA, DVI and HDMI. It just says no Signal for the input I select manually.

Did you try all the input mode, AUTO, DIGITAL, and ANALOG? Remove the graphics card, and connect D-sub (VGA) from the motherboard. If it still doesn't work, you may have a defective motherboard.

I removed the GPU but there still is no signal. You select the input mode by hitting the menu button on the monitor right?

A. Motherboard failure - check the manual for motherboard indicator
B. CPU Power not plugged in - well, it's a stretch, but let me try extreme. check all the cables.
C. Monitor failure - you can verify this by connecting oth er computer already functional

Depending on model, some have source button, others you have to navigate menu. No matter what, the monitor should show its input mode.

Well After looking at the mother boards manual I couldn't find anything on a mother board indicator. I holed the monitor up to another computer and tested it and it worked and I am pretty sure everything is connected I have the JPWR1 and the JPWR2 cords connected.

If it would help I can take pictures of the computer and you can see If there is anything weird about how I set it up.
Also what are some common characteristics of a motherboard failure that I might be looking for?

Once I plugged in power switch connector wrong way , and obviously the PC wouldn't boot up. Consult your motherboard manual once again to make sure all the internal connectors are keyed in right way. Some of those tiny pin connectors are confusing, and it's easy to connect wrong way. Also, it's very rare, but once I saw someone plugged in wrong cable to CPU power socket on the motherboard. The socket is keyed, so the connector wouldn't fit, but somehow he managed to push it in. On your motherboard, CPU power socket is located on the right side edge between CPU and I/O ports. 4 holes are keyed. Defective motherboard is just defective. I don't think these days you can see much visible sign of failure. It can be a chip set problem. Frankly, if you can't identify a real problem, usually you call it motherboard issue in something like this.
