I've seen similar errors on an old Abit BX-133 mobo. After swaping several 
parts, to no avail, I gave up on that. Thought I could live with some 
annoying messages. Then came spontaneus reboots, happening more and more 
often, and the rate of the NMI messages started to rise also. It turned out, 
that several capacitors were leaking, so I threw out the board. I've no way 
to confirm it, but I guess the NMI messages were caused by that, so it's 
quite possible that you have some power problems indeed.

cheers,
m.
