The computer is strange, and I usually use two DVD CD-ROM drives in my computer.Now one of the two DVD CD-ROM drives is inserted into the machine or the two is inserted together, and the machine opens for a few seconds, and automatically reopens the machine automatically after the machine is extinguishing.The power line of the two DVD drive is pulled out.Open the machine, no problem.One of the DVD drives will also open the machine indefinitely.This situation does not appear before, before also used two DVD CD-ROM normal, today may have this problem to me, the original computer no problem, open the machine inside the first is inserted with a DVD CD-ROM, then switched on, I will forget the boot state, another DVD CD-ROM also connect the poweR线突然起火……吓得我马上关掉机器。也许是我让它导致DVD光盘插入电脑。然而，这是不了解，火只是一个DVD光驱，我用另一个DVD驱动器，不产生火花的电源供电和自动灭火机。我的力量是神奇的350 ` ` 300w.some人在网上说，短路也缺乏电压。如果还不够的话，我以前就不能用了，我的电脑配置也不是很差，可以教我如何好好利用这两个光驱。



网民分析了答案：

1。首先，电子设备发出火花，解释损坏，不使用，以免影响其他部件，可以拉出主板和硬盘的电源，拉出光驱的数据线，然后分别连接光驱，以测试开关盒是否正常。

2。在你说的情况下，可能有一个CD-ROM驱动器和一个短路。你的光驱连接到同一个IDE线路上IDE线也可能有问题。
