I have tried everything , my business requires that my system boot up at 5:30 every morning , i have replaced Everything , PS , I have even went as far as to install a Line Conditioner Transformer , the Company I bought it from Essencomp.com will not stand behind it I will forward their resonds at your requst they say all they can do is sell the motherboards they cannot trouble shoot them , but they will not repalce it either ! anyway help with this problem , maybe it is an internal thing , but it has worked in the past with the same model board
