I just built my 2nd computer. This one will not give a display on the monitor. The monitor actually goes into standby mode as if it's not receiving a signal from the computer. The computer is powering up, video card is running, cpu passive heatsink is getting warm so I'm at a loss right now. All that I have hooked up is the video card, hdd, dvd drive. All internals are brand new. Could the ram or mobo be bad? I would say ram first since everything seems to be getting power and doing what it looks like it should. But would ram cause the monitor to not recognize a signal?

little specs would help.
make sure the Clear CMOS jumper is not in "clear cmos"
if u have another PC, start testing the parts there one by one

I believe that it's an auto detecting LCD.
I swapped out the RAM for the other stick and still no go.
I swapped out the video card with my previous and still no go.
The harddrive is carried over from my previous build
So basically that leaves the motherboard or cpu, correct?
Would I be doing any good by connecting the monitor directly to the motherboard?

Reassemble the PC outside of the case, with the mobo on the mobo box. Start up the PC by jumping or connecting the two power pins on the mobo with a screwdriver. If you get video then, something inside the case was shorting out the mobo. Look for a loose screw, wire, cable, misplaced screw, etc. Something that shouldn't be there.
You can't just start it up normally while outside of the box?
I took the video card out and connected monitor to the motherboard for onboard video and still get nothing for display.
So now I have mobo, cpu w/ heatsink, 1 stick of memory, 1 hdd, and power supply.
Final result : I RMA'd the board.
However, I think I found the probable cause. To install the CPU heatsink (NT06-Lite), you have to add a mount to the bottom of the board and insert screws through the board with posts and washers. I added the washers on the bottom of the board instead of the top. So the posts on the top of the board tightened down on the top board and traces. When I took this all off to package the motherboard I noticed that the traces were now exposed so I bet that the traces were shorting to the posts. That's my guess.
