Please check the signal cable?

Question

Whenever I try to open my computer it says in a red rectangle with black letters "Please Check The Signal Cable" I don't know how to fix it or what the problem is. Also, whenever I press the start button on my computer it makes a long beep with another long one after then continuing on beeping. This is beginning to get very annoying and I would like it to be fixed immediately. Please reply.
