    CPU FAN not spin is not meaning that the problem is completely based on the system FAN. In some cases, might be power supply of the system has not been capable to make this connection. In that case, you can make sure all the connections, special power supply connection with the motherboard has been connected properly or not. If it is not work, you need to fix this issue with the replacement strategy.

    I checked in my computer case and at least four capacitors are dead or dying. Jumper setting is also making proper connectivity task onto this task. Hence I would be suggest to you that first try to jumper setting task onto it and then try this connection on your Dell XPS 600 desktop pc. Manual of the desktop pc will be work to fix this connectivity task onto your desktop pc. Hence try this and check what result arrives onto it.

    If the power light is off, reseat the power cable into both the power connector on the back of the computer and the electrical outlet. Also you need to check all the connection of the power supply. If there is any mistake present on it, in that case, you need to replace it with the other PSU. This is helpful to you for fixing your power connection problem.

    If the power light is blinking amber, ensure that the voltage selection switch is set to match the AC power at your location. In this case, jumper setting makes an important reason onto it. jumper setting mostly done with the help of the manual of this motherboard. Hence use the connection mentioned on the manual and applies it onto the motherboard. This will be work to fix your connection problem.
