First question: are you overclocking?
Second question: is it just Asus probe that reports this voltage? The ATX 2.1 specification says that the max tolerance on +12v is 5% - so 13.6v is definitely out of spec!
 
What about if you check what the BIOS is reporting? Some motherboard monitoring programs are not so hot at reporting what the motherboard is actually doing. Have you tried MBM instead?
 
If BIOS is reporting the same voltage levels, the first thing to try would be to go into BIOS, and load the optimised defaults (you may have to go back and change a few things like disk boot order and the like) and see whether that makes any difference
 
Report back and let us know whether that helped or not.

I am also having somewhat of the same problem. To answer your questions, AndyFair, I have checked the monitoring in the BIOS, and it is the same as the utility used in windows (asus probe). I'm around 13.44v running an AMD Athlon 2000+. This is on a spare computer, so i really don't do much gaming. However, I find that it will restart or freeze frequently. I even changed power supplies a few times, but it still does the same thing. Let me know if you have any more suggestions!
 
Thanks,
Matt
