Default Monitor won't get any signal

Well recently I turned my computer on and my monitor wouldn't get a signal. My motherboard had problems in the past, so I replaced it. I checked my monitor on another computer, and it worked fine. When I turn on the power all fans come on. Including the fan on my graphics card. Any idea what it could be? Here are specsGeforce 9800gt cardQ6600 processorBiostar g41 dvi motherboard4 gb of corsair ram

What is your PSU make and wattage? Sounds like you aren't supplying enough power to the board.

No signal is a connection issue, try to re-seat all connections from the monitor and to the graphics card, try to connect to an integrated connection on the motherboard.
Try to use a different kind of cable hdmi, vga or dvi.

Also check the simple stuff. Make sure the monitor is on the correct source mode, and that all the connections are secure.

If none of this works unplug the monitor from the computer, and power cycle the computer and monitor.
