mac mini core 2 duo won't turn on

Good evening,

my name is daniele and i’m Italian. I found this site from google because I have a problem with my 2008 mac mini (2.0GHz intel core 2 duo): it won’t turn on. No fan noise, no led up, nothing. My power supply works, I tried to reset SMC, now I’ll change the PRAM battery. I would tell you what are the most frequent problems that the mac mini occurs. If you can help me, I’ll be very happy.

Thanks at all,

Daniele

p.s. my English isn’t so good, I hope you understand
