电脑声音不正常的解决方法

电脑声音不正常的解决方法 在电脑的日常使用中，我们有时会遇到电脑声音不正常，比如: 1、电脑声音大; 2、电脑声音小; 3、电脑声音失真; 4、电脑声音嘶哑; 5、电脑声音突然没了; 6、电脑声音很卡等。 下面，天诺时空的电脑专家，帮你逐个解决。 绝大多数朋友的电脑一般情况下来都是用来听歌上网看电影，都是拿来娱乐的。因此声音就成为其不可或缺的一部分了，可是许多朋友的电脑声音经常出现这样或者那样的问题。绝大多数都是由于不正确的操作所造成的，当然少数情况下也包括硬件问题，今天就跟大家详细的一下电脑没声音的故障判断方法，以及解决步骤。 硬件故障:检查音频设备是否损坏，我们可以拿我们自己的设备换到其它电脑上，看看是否依旧有此问题。之后如果还存在问题可以参考这篇文章电脑没声音硬件问题解决。 软件问题:许多朋友都遇到过这样的问题，在使用杀毒软件查杀病毒之后电脑就没声音了，其实这是由于病毒感染音频文件所致，杀毒软件无法清除病毒，所以只有把感染文件一起删除。 驱动问题:根据我多年的维修案例来看，绝大多数电脑没声音的原因都是由于此原因造成的。所以此项是我们讨论的重点。首先如何判断我们的电脑没声音的问题是由于驱动问题所造成的呢,首先打开电脑设备管理器，具体方法是“控制面板/系统属性/硬件/设备管理器”，也可以右键我的电脑选择属性然后点击硬件进入设备管理器列。接下来查看是否有黄色的问号或者感叹号，如果是黄色的感叹号表示是没有装的驱动，如果是感叹号则表示是由于声卡不匹配所造成的，如果是感叹号则右键选择卸载即可。如果是问号，则需要重新安装一下驱动，对于对驱动完全不了解的朋友，可以下载“驱动人生”或者“驱动精灵”，安装完毕打开后会自动提示你安装驱动，点击更新它就会自动安装。对于有经验的朋友，建议你去官方网站下载最新的声卡驱动，那样的驱动会比自动下载的效果好一些。 如果是不能联网的朋友，或者是用驱动精灵、驱动人生不能更新的朋友，建议下载一个驱动包，这个驱动包包含绝大多数电脑的声卡、显卡、网卡等驱动。大家可以去“天诺时空”下载，注意看清自己的系统，然后下载对应的驱动包。我的U盘里面就放了一份Windows XP和Windows7的驱动，这样别人让修电脑，碰到关于缺少驱动的问题，直接拿出来就可以用了。需要声明的是，这种方法只适用于声卡出现黄色问号的时候才能用，因为它不会自动更新你的驱动，碰到已source of inexhaustible power and to promote economic and social development.
