maybe one hours,maybe two minutes.when it is booted,all of it is ok.but suddenly,it will
shutdown automatically.I check the power cord,that is in good condition.Who can give me some advise?thanks

 

Maybe it's time to reinstall your fiery or upgrade to the actual version. We use Fiery IC-408 with embedded windows xp system, and it's not very stable, we have the same problems sometimes.
