There are few reasons why this could be happening, could you answer a few questions about it?
1. Does the PC boot (lights on and a humming from inside)?
2. Do you have a spare monitor you could try?
3. Is the cable plugging in to the board or a card?
3a. If the latter, is the card fitted correctly?

You say you hooked it up to your laptop, I assume it refers to the tower?
If so, It sounds like your monitor is faulty. If you plug it in to the mains and don't connect the PC, do you get any messages on the screen?
If you mean that you hooked the monitor to the laptop and it works fine, you may have a loose connection in the tower. If you are feeling confident, unplug it all and open the side to see if there is anything loose, this however may void your warranty.
Let me know what you find.

Are you in a position to open the PC case?
If so, can you check if the monitor plugs in to the motherboard or to a graphics card?

Just so that I have everything straight in my head...
You can't get a picture when you plug the monitor in to the PC.
You can get a picture when you plug the monitor in to the Laptop.
You can get a picture when you plug the laptop in to the PC.
If the above is correct then the only reason I can think that it wouldn't be working is down to resolution. If the PC is set to use a resolution that is "out of range" of the monitor's list you wouldn't get a picture at all.
Can you plug the laptop in again and check what the screen resolution is set to?

You can get a picture when you plug the monitor in to the Laptop. RIGHT
You can get a picture when you plug the laptop in to the PC. DON'T KNOW HOW
I can't check anything on the pc because I can't see the monitor. Am I missing something?

No, you aren't missing anything. I thought you had somehow managed to get your laptop running as a monitor.
I'm sorry to say, I think the integrated graphics on your motherboard is broken.
This leaves you with two options on this particular PC...
1. Fit a new motherboard.
2. Try fitting an external graphics card.
