Nothing shows up on the monitor when I power up the computer

I switched two motherboards into two different cases....and didn't swap the power supply. And now when I power up the computer, nothing shows up on the monitor!!

I know the monitor's fine because I just used it 20 minutes ago...should I swap the power supplies as well? The video cards are also in working condition....so I'm not sure what I might have done wrong...

did you swap everything else from the cases (vid card, HD, Memory, drives) or just the motherboards?

if the two computers are different types of processors, the power supplies might not be equivalent, so swapping them could help.

Are you getting absolutely nothing or are you getting that "Check Signal Cable" message?

Is the computer powering up? Do the fans start turning and can you hear the hard drive as well? It doesn't sound like it's the monitor from what you've told us.

I would double check the power connection between the motherboard and the power supply. If it is ok, then I would check the cable connection between the video card and the monitor. Normally, you could hear a beep sound from the PC speaker when the motherboard is power up and running. That tells you the motherboard is not dead. If you don't hear anything from the motherboard, then there are 3 possibilities:
1. your PC speaker is not hooked up to the motherboard.
2. your motherboard has no power going into it.
3. your motherboard is dead.

Is the monitor turned on? Plugged in?

Seriously though, maybe the monitor's dead. Does it work at all? Try different computers and see if the monitor's still alive.

This sounds stupid, but make sure the contrast is up high enough and brightness as well. (It happened to me once).

Yeah, I did that contrast thing once too!! hehe, unfortunately...this problem isn't as simple as that =/ although I wish it were....I tried the computer on different monitors, including the one I'm using now....so it can't be the monitor...the connections are all good....in fact, I took it to a shop to get it checked! And it worked fine!! OUTSIDE OF THE CASE.....the only prob was the memory....so I had it exchanged....and now

it's in the case (which I'm guessing is the problem??) and it still won't show anything in the monitor......I don't understand how the case can affect it though...the only thing that the motherboard is using in the case are the power on, reset, hard drive led...etc etc jumpers......

so is it the CASE??? or am I still not doing it right..??? =/

I'm going to try switching it into a different case....but I'm getting so frustrated, I'm ready to give up on it....

any help is appreciated ......thanks to everyone who's been posting and helping me out =)

Since it doesn't work in the case, make sure nothing it shorting the board to the case (loose screw, standoff, etc).

Second that notion. The board's probably shorting somewhere in the case. Check the screws that hold the motherboard to the case, make sure those insulating washers are in between the screws and the motherboard. That happened to me with my current system when I built it.
