Hi FartyMcCrabLice
same problem with my computer
Asus A8N5X
AMD Athlon 64 3000+
and other stuff........
i was searching for weeks - no result.
But it doesn't depend on the powersupply - i've replaced it with another type
--> no result.
Every USB Device (HDD, Cardreader, mouse) ist running
To get the computer up again --> unplug the power (wait 3 sec for the elkos) then i'm able to turn on the pc via ATX PowerON Button
Within the bios configuration i've found nothing about "Wake on USB - bull****" whatever.....
