Hmm...
First check if ur old SMPS is working by pluging it in the mains and shorting da green and ny black wire(use any small piece of stray wire). The SMPS fan will start spinin indicatin the SMPS is working fine. If it doesnt send ur SMPS for repairs.
Usually always do the above before installin a new SMPS to check for faulty SMPS's
If the SMPS fan starts spinin then check the motherboards power connections and still if the system doesnt boot up.. then most probably ur new SMPS has burnt ur "SouthBridge" send ur mobo for repairs.


btw always by a good branded high end SMPS(pwrsafe etc) coz they hav a inbuilt feature that prevents any damage ur mobo incase of a short in the SMPS..
hope this helps
