[URGENT]Monitor turned reddish. Restart but "no signal"

[ChristyA]

I was about to install something and watch a video, but there wasn't any sound coming out. I try to set the speaker's volume in my PC, but it wouldn't work, so I unplug and re-plug my speakers. And then the monitor suddenly turned reddish. This is what I see: http://oi58.tinypic.com/n5h5hu.jpg or http://postimg.org/image/91xwmn7c7/

And so I restart my computer but the monitor says "no signal". What should I do?
Please help me ASAP I have a huge project to do TAT

what type of connection do the speakers use? HDMI/3.5mm Jack/ etc

In any case its clear something went wrong - you probably had a leaking electricity through the cable because of incorrect wiring or bad speakers/monitor (not your fault either way).

The question is what broke? First thing to try is another monitor - see if that works, if it doesn't then its likely your PC and we'll continue troubleshooting.
