So, what's your problem. Does Windows run? Does the computer overheat? If the answers are "yes" and "no" then congratulations - you have a nice, quiet computer there.
BTW, when you say the fan spins then stops, are you looking at it or just going by the noise it makes?

You are still being quite economical with information.
From what you have said so far I read that:
1. This is a new build.
2. You bench tested it, without problem, before putting the components in the case.
3. Now that you have put it in the case it won't start. The fans spin momentarily then everything goes dead.
If those assumptions are correct then the most likely explanation is that you have created a short-circuit when installing the motherboard in the case. The most common cause is not using the correct stand-offs.

I would agree with ijack, another possible solution is to unplug and carefully re-plug all the connections in and try again. I have to warn you though, i have had this problem twice, and both times it was my motherboard that was faulty / blown.
If you think..Fan is ok.it is not getting enough power from mobo Fan Header to spin.. unplug the 3 or 4 pin Cpu-Fan Connector, locate the
power+ wire (usually RED next to BLK- wire on corner) cut RED wire close to connector and isolate the connector end, splice the other end coming from the Fan.Connect Cpu-Fan to its Header with RED wire cut and isolated. now locate any other nearby Fan Header or +12V Pin to tap
spliced wire into, if the wire is not long enough you can add-extend it with similar wire and preferably place a diode in between for protection. This is
how I found the by-pass the similar issue,saving replacing culprit Cpu or Mobo.to start everything from scratch. This fix will let your CPU-Fan so
your Pc to run, however Fan Speed will be Constant to Max.Fan is now recognized and speed wil be reported in hardware monitor.Please let us know if this helps you to fix the issue. but, does any body know what is the cause of the problem..? This Fix is Provided by: TEKNOFiX - 2014
