My son knocked over the tower on my PC and the monitor turned off. Now I can't turn it back on. It keeps saying 'no signal detected'

I have unplugged everything - plugged it all back in - even got a new monitor (an old one from a broken computer we had) and hooked that up - no good.
I tried a different cord.
I opened up the whole thing and cleaned it out. (although I suppose if anything was unhooked inside there I wouldn't know...) I have windows xp if that means anything...

Any other ideas?

Thanks SO MUCH for any help =)

That message means the display is not receiving a signal from the video card. Please make sure the video card is properly seated and all cables to and from the video card are properly connected.
