Failure phenomenon: buy two 2GB of memory, which is to plug the computer on the black screen.The power key cannot turn off (only long press), and it is still impossible to switch on my original memory.If the memory is not plugged in, even the alarm is not.The CPU fan is turning, but the hard disk doesn't seem to react, because the hard disk lights are not bright.

解决方案：电源的功率小，和改变电源的问题仍然是，它突然想起以前的内存和处理器有超频，和内存板没空主板BIOS之前，它改变了记忆。所以新的记忆仍然可以在旧的内存的超频设置，也将启动破坏自然。清理主板BIOS后，它终于可以开始。
