What do you mean by this: everything is working fine?
No, I don't think so that there is any problem with your monitor or may be there is. First you need to check your cabinet. See if everything is working fine there, I mean the fan, hard disk, and other devices. If everything is working fine, then you may try one thing. Just safely remove all the connectors, wires, and other devices connected to your system motherboard. And then reconnect them. See if it works.
