Re: Processor fan doesn't start
No, it's not normal. Make sure you have the cpu fan plugged into the proper mb plug. It should not be plugged into a chassis fan plug or your cpu will severely overheat. On the mb there should be either a 3 pin or 4 pin that is marked cpu fan. It will look exactly like the chassis fan pin group but that one will be marked cha fan. If it is plugged into the proper area then you may have a faulty cpu fan. Replace with a new one and see if that fixes the problem. Hope this helps & please remember to rate my answer. Thanks.

The processor sounds as if it is not being held by the CPU locking device. Get it re-installed and you should be okay. It is just a case of removing the cpu fan and heatsink ( while the power lead is unplugged of course) lift the locking lever (dependinding on the processor type) and reseat the processor, lower the lever and lock in place. try to give the cpu a wiggle, but not too hard, as long as it doesn't move then rebuild the computer and try it out. Good luck, and don't try it as if you are removing a six inch nail with a mallet. It should come to bit easy enough.
Try swapping the power button connection with the reset button connection. Then to turn on your computer you will need to press the reset button. If that works you have a faulty power button. Otherwise try using a different PSU. One that you know works. If that doesn't help the motherboard will have to be replaced.
Emachines (the older ones) are bad for the thermal paste to dry up causing the processor to overheat,pick some up at radio shack and remove the heatsink from the processor and put a light coat on top of the processor then replace the sink. Are there any beeps coming from the pc? Does the fans kick on? Try opening the case and pulling a stick or ram and restart if no luck replace the other stick with the one you pulled first.If all that doesn't work I have seen a power supply go bad and do just that. I know it may be a lot of ifs but its a place to start!!! GOOD LUCK
That could be a problem with the heatsink/fan assembly on the processor. It sounds like the processor is starting up, getting warm as they do, the fan starts up but does not cool efficiently enough and forces a shut down due to heat. Clean out the fan assembly and replace the old heatsink compound on the processor heat sink. Hope that helps.
1.Processor may be overheated,because the processor fan may not be rotate.
if processor fan is rotating then...
2.Remove the Hard disc power connector and data cables then try to on the computer.
3.Remove the Cd/Dvd drive power connector and data cables then try to on the computer.
4.Remove any other drives connected with your computer.
5.Remove the printer,scanner,mouse,keyboard connected with your computer.
thank u .... now u can find the problematic device. All The Best...
take proc. out and check if you bent any pins when replacing it. make sure you installed it correctly. some motherboards wont boot if cooling fan is not connected to motherboard. make sure motherboard supports new proc.
As I see your system is a bit old so the fan may be broken. try to replace it with a new one. Those fans are very cheap today. Do not use your computer without the processor fan. I am sure your problem will be solved!
