Computers on but no signal on monitor

Acer M3802

Specs: Windows 7
I was just wondering if anyone would be able to help. I've had my PC for around 6months, when i first got it, the monitor turned on and then came up with no signal, once i figured around with the cable it was fine, I've now moved and have connected up the computer, but the monitor is again coming up with 'no signal' i've connected the monitor to the laptop and it works fine. I've tried another monitor on the computer and again it's coming up with 'no signal' and i don't really no what to do, or why this is happening, as the computer is relatively new.
Any help would be much appreciated.
Thank you

If it's that new, and still under warranty, take it in for repair.

It's obviously not the monitor. "No signal" means just that...the monitor's not getting a signal. The video card is either bad or loose. If you have an actual video 'card', open the case & make sure it's seating fully in it's slot. If you have onboard video, it may be defective...if that's the case, install a *real* video card.
