戴尔VOSTRO1400自带的工具检测出机器的如下问题，是什么的问题？

sata disk s/n=5maayr39-s.m.a.r.t.long self test
用戴尔自带的检测工具检测出这样的信息
好像是硬盘有什么问题
但是又不能确定到底是什么

因为机器最近总是蓝屏
而且越来越频繁
所以按照说明书上的检测方式检测了这个问题

请高手给予帮助
不胜感激~

附蓝屏写的

回答：

Dell的检测工具如果检测出错误都有XXXX-XXXX的这样的代码的。所以你那个提示应该不是什么硬件错误提示。如果机器有叫的话，你看有无上述代码。

下面的蓝屏信息应该是你8400显卡出现错误。软件先看下更新驱动（oem版本的就可以了）或者重装下系统。
