    I'm immediately led to thinking that it's a problem with the video card. Try reseating the card itself (might have come loose). If you have onboard graphics, run the system on that to see if it works.

    Sorry about that lol ... Open up your tower .... the slot that your monitor plugs into at the back of the tower - that's your video card slot. Just make sure that it's firmly in place in its socket. If you take out your graphics card (video card), are you still able to plug your monitor into something? If you are, then you have onboard graphics which means you can take out your graphics card and that way you'd be able to test whether it is in fact the card at fault ....

    Hope that's toned down enough :)
