一日,朋友打来电话向笔者求助,说刚升级的机器刚开始还能点亮,几分钟后便死机了,再开机就没有一点反应。打开机箱,便隐约闻道一股焦味,仔细察看主板上的电器元件,发现主板的北桥芯片附近有烧焦的痕迹,很明显主板已经牺牲了,但是导致主板烧毁的原因是什么呢?首先检查了电源;电压输出都很稳定,所以可以排除电源供电的原因。由于CPU与内存仍可使用,基本可以排除它们对系统的影响,最后将检查的重点放在了显卡上。 他这次升级只换P4赛扬CPU、i845D主板、DDR内存,显卡 One day, a friend called to the author for help, said the newly upgraded machine can only light the beginning, a few minutes later crashed, and then boot no reaction. Open the chassis, then vaguely heard a smell of coke, carefully look at the electrical components on the motherboard and found that there is burned traces of the Northbridge chip near the motherboard, it is clear that the motherboard has been sacrificed, but led to the motherboard burned what is the reason? First Check the power; voltage output is very stable, so you can rule out the power supply. As the CPU and memory can still be used, you can basically rule out their impact on the system, and finally check the focus on the graphics card. He only for the P4 upgrade Celeron CPU, i845D motherboard, DDR memory, graphics
