高端主板都有的电路保护，不断电的时候启动就不会出现这个现象，断电了以后启动时检查一下电路，就是这么设计的,没有问题。

　　在别的版块看到过类似的提问，有人在华硕的官网上面找到解决方案，说事升级一下bios就好，华硕说的这个问题是不管断不断电，启动都需要两次，这个是bug问题不一样。

　　可以尝试更新一下主板的BIOS，下面是摘自外籍网站的最版本的BIOS，无奈国内官方最新只有1003版本的BIOS，估计还没主板上的新!

　　Change Log -

　　- Removes full reset at POST (double post) on cold boot or auto overclocking routine.

　　- Improved OC performance using Multipliers or Auto Overclocking

　　- Improved BCLK and DRAM OC capabilities when enabling the “Internal PLL Overvoltage” option in BIOS.

　　- Minor Bug Fixes including Auto Rule for C1E, C3, C6 is returned to Enabled first (1253 disabled first) and improved USB compatibility.

　　- Enabling Internal PLL Voltage will still cause resume/hibernate issues (Intel related) but we are working with Intel on any potential workarounds. For those users not needing a 47x or higher multi on the K series we recommend leaving this option disabled.

　　- User reported Per Core setting not saving properly has been identified and will be fixed in BIOS 13xx shortly.
