Having problems with your Dell OptiPlex SX270 PC Desktop ?

Computer does not start. Replaced motherboard and RAM. Hear the fan when I start the computer

\015 I have a Dell Optiplex SX270 which stopped working. I replaced the motherboard with a new one and have also replaced the memory (RAM). But there seems to be no change. When I press the start button, I see yellow/orange light on the motherboard and the green light under the start button. I also hear the fan running. But I don't see anything on the monitor and if I click on a button on the monitor, I get the message "check signal cable". Please help.\015

Answers :
