A friend of mine had a similar problem. He exchanged the mobo and the problem's
gone.
Your computer is new, so it wouldn't be any problem even you never turned it on
once.
So my guess is that your mobo may have small problem or maybe (just maybe), your
cmos bettery is low in power.  Contact you computer dealer to get an exchange
bettery to see if it's ok.  if not, you may need to change the mobo.
