What Happens: In this case Monitor is taking
pc repair picpower from Main Power supply unit. Here from the input  point of the power supply unit power is comming by parallel process to the outlet of the monitor.So there is no relation between power to the monitor and to the CPU.Here the input voltage is 220 volt which is comming to the monitor.So the main problem is with the Power Supply Circuit. If the power supply is damaged then the fan will not move.
Cause & Solve:  1) The fuse of the Power Supply Unit can be burned so it should be checked. If it happens then it should be replaced.
2) In the power supply unit you have to look for that no parts(Resistance,Diode,Capacitor) of it has not been burned or not.If something is burned then it should be replaced.

3) If by the above ways the problem is still then you have take help of a Multi Meter/AVO which can measure any parts that you feel not well.If any fault in any parts is detected then should have to be replaced.
4) Even in many cases Dry soldering is needed to solve this.
