Monitor won't get power nor signal, worked yesterday

[MartiNeo]

So the title is pretty self-explanatory; I have a monitor (actually I have three monitors), and it worked fine yesterday, turned off my computer and now it won't get any power, e.g. power light won't turn on, nor will my computer register that there is a monitor there.
I use a HDMI cable, and a HDMI to DVI adapter to connect it to my screen. I tested the power cord and it works with my other monitors, I've also checked if all the cables are properly connected.
Please help // Martin

If under warranty, try RMA-ing it.
