Mac Pro has Insomnia!

[mrt209]

Just as myself, my Mac Pro has insomnia...

Whenever I put it to sleep, it'll turn back on after 3,4 seconds. I started noticing it a 9,10 days ago when every morning my Mac Pro would be on even though I put it to sleep the night before.

Currently I'm running 10.6.7 and I've tried closing all apps before putting it to sleep. I initially thought LogMeIn or Splashtop Remote was causing this, but I've closed both apps and it still didn't go to sleep.

Any ideas how to fix it or what's causing it?

Thanks!

Try checking Console after it wakes itself up to get some more information on what's going on. That should help narrow down which process is causing this.

Did you change any hardware or software just before this started happening?

USB peripheral? I've had this a few times: a SD card reader and my Garmin satnav are both known culprits.
