I also had problems with this BIOS version - instead of seconds shutdowns or restarts took more than one minute. After resetting, refreshing etc. with no success i manually enabled/disabled all external components in BIOS and figured out, the sound-chip was issuing this problem.

 

So i installed the latest audio-drivers from the support site and suddenly the problem was solved.

 

Maybe you have the same problem.
