故障现象一:显示器黑屏 排除方法:1、先确定是否是显卡有问题。判断的方法是听PC喇叭的叫声,一长两短声肯定是显卡发生了致命错误,只能更换。 2、如果无法断定显卡的好坏,可以换一块试试,还不行的话则有几种情况:一是显卡未插紧,另一种情况是显卡与主板插槽的接口太脏,造成接触不良,可以用橡皮擦一擦。还不行的话,换个插槽(仅对PCI显卡,因为AGP插槽只有一个),一般来说,这个问题在同时配有PCI声卡并把PCI声卡插在PCIl或PCI2槽上(即靠近AGP插槽的PCI插槽)时最容易出现,将PCI声卡换插到PCI3或PCI4插槽上往往能解决问题。
Symptom 1: Monitor screen troubleshooting: 1, first determine whether there is a problem with the graphics card. Judgment is to listen to the sound of PC speakers, a long two short be sure to video card has a fatal error, can only be replaced. 2, if you can not determine the graphics card is good or bad, you can change for a try, if not, then there are several situations: First, the graphics card is not tight, the other is the graphics card and the motherboard socket interface is dirty, resulting in poor contact , You can rub with an eraser. Not enough words, another slot (only for the PCI graphics card, because the AGP slot only one), in general, this problem at the same time with the PCI sound card and the PCI sound card inserted in the PCIl or PCI2 slot (ie near the AGP slot Of the PCI slot) is most likely to appear, the PCI sound card for plug into the PCI3 or PCI4 slot can often solve the problem.
