电脑显示器会突然黑屏,重启后又正常过会又黑屏, 电脑显示器会突然黑屏，重启后又正常过会又黑屏，黑屏时间不等，有时几分钟有时几个小时。。。,,,到底是显示器问题还是主机问题呀, , 这与显卡的驱动和显示器的设置有关，有时显卡调整显示时就会暂时黑屏，但对系统本身不会有所影响。可以试试更换显卡驱动。如果有加载第三方的显卡调整软件，可以试试卸载掉看看。 谢谢采纳 , 计算机显示器出现黑屏是用户在使用计算机中经常遇到的问题。其实，只要稍对计算机硬件中主板、CPU、内存、显示卡等几大部件有一定的了解，非元器件的损坏的简单故障完全可以自己动手排除。出现这种情况，你可以按照以下的维修步骤和进行分析和简单的维修: 1(检查主机电源是否工作;电源风扇是否转动,用手移到主机机箱背部的开关电源的出风口，感觉有风吹出则电源正常，无风则是电源故障:主机电源开关开启瞬间键盘的三个指示灯(NumLock、CapsLock、ScrollLock)是否闪亮一下,是，则电源正常;主机面板电源指示灯、硬盘指示灯是否亮,亮，则电源正常。因为电源不正常或主板不加电，显示器没有收到数据信号，显然不会显示。 2(检查显示器是否加电;显示器的电源开关是否已经开启,显示器的电源指示灯是否亮,显示器的亮度电位器是否关到最小,显示器的高压电路是否正常,用手移动到显示器屏幕是否有“咝咝”声音、手背汗毛是否竖立, 3(检查显示卡与显示器信号线接触是否良好。 可以拔下插头检查一下，D形插口中是否有弯曲、断针、有大量污垢，这是许多用户经常遇到的问题。在连接D形插口时，由于用力不均匀，或忘记拧紧插口固定螺丝，使插口接触不良，或因安装方法不当用力过大使D形插口内断针或弯曲，以致接触不良等。 4(打开机箱检查显示卡是否安装正确;与主板插槽是否接触良好。 显示卡或插槽是否因使用时间太长而积尘太多，以至造成接触不良;显示卡上的芯片是否有烧焦、开裂的痕迹;因显示卡导致黑屏时，计算机开机自检时会有一短四长的“嘀嘀”声。安装显示卡时，要用手握住显示卡上半部分，均匀用力插入槽中，使显示卡的固定螺丝口与主机箱的螺丝口吻合，未插入时不要强行固定，以免造成显卡扭曲。如果确认安装正确，可以取下显示卡用酒精棉球擦一下插脚或者换一个插槽安装。如果还不行，换一块好的显卡试一下。 Is team-oriented and team building.

Perfect village , 有时候是电源问题有时候是主机的问题 , 解决自动重启的方法， 我的电脑，右键属性,,,,高级,,,,启动和故障恢复,,,,设置,,,,系统设置,,,,自动重新启动(去掉前面的勾)，，保存～ 或者可以考虑下安全模式全盘扫描病毒 木马 恶意软件 或 重做系统看下 如果还是重起 在考虑硬件如内存， 重新插拔硬件和线 清理灰尘 替换电源试一试的 , 声音还能持续几秒后就没了，，这说明不是液晶显示器的问题。 小机箱散热不好，夏天温度太高，电脑运行较长时间后热量散不开，就会导致电脑死机或自动重启。 你可以拆开机箱，看CPU与显卡的风扇是否正常转动，如果一切正常，你可以尝试，用风扇对着机箱吹(要打开机箱盖)，然后运行较大游戏(软件)，如果不再出现问题，说明就是散热不良，建议可以换个机箱。本来现在的CPU和显卡的运算能力大幅提高就带来了散热量的提高，小机箱是中看不中用的东西，最容易出现像你现在的情况。 , 计算机重新启动 一、软件方面 1(病毒 “冲击波”病毒发作时还会提示系统将在60秒后自动启动。 木马程序从远程控制你计算机的一切活动，包括让你的计算机重新启动。 清除病毒，木马，或重装系统。 2(系统文件损坏 系统文件被破坏，如Win2K下的KERNEL32.DLL，Win98 FONTS目录下面的字体等系统运行时基本的文件被破坏，系统在启动时会因此无法完成初始化而强迫重新启动。 解决方法:覆盖安装或重新安装。 3(定时软件或任务软件起作用 如果你在“计划任务栏”里设置了重新启动或加载某些工作程序时，当定时时刻到来时，计算机也会再次启动。对于这种情况，我们可以打开“启动毕睿 觳槔锩嬗忻挥凶约翰皇煜さ闹葱形募 蚱渌 ㄊ惫ぷ鞒绦颍 淦帘魏笤倏 觳椤5比唬 颐且部梢栽凇霸诵小崩锩嬷苯邮淙搿癕sconfig”命令选择启动项。 二、硬件方面 1(机箱电源功率不足、直流输出不纯、动态反应迟钝。 用户或装机商往往不重视电源，采用价格便宜的电源，因此是引起系统自动重启的最大嫌疑之一。 ?电源输出功率不足，当运行大型的3D游戏等占用CPU资源较大的软件时，CPU需要大功率供电时，电源功率不够而超载引起电源保护，停止输出。电源停止输出后，负载减轻，此时电源再次启动。由于保护/恢复的时间很短，所以给我们的表现就是主机自动重启。 ?电源直流输出不纯，数字电路要求纯直流供电，当电源的直流输出中谐波含量过大，就会导致数字电路工作出错，表现是经常性的死机或重启。 ?CPU的工作负载是动态的，对电流的要求也是动态的，而且要求动态反应速度Is team-oriented and team building.

Perfect village 解决办法:更换RESET开关。 还有机箱内的RESET开关引线短路，导致主机自动重启。 8. 主板故障 主板导致自动重启的事例很少见。一般是与RESET相关的电路有故障;插座、插槽有虚焊，接触不良;个别芯片、电容等元件损害。 三、其他原因 1(市电电压不稳 ?计算机的开关电源工作电压范围一般为170V,240V，当市电电压低于170V时，计算机就会自动重启或关机。 解决方法:加稳压器(不是UPS)或130,260V的宽幅开关电源。 ?电脑和空调、冰箱等大功耗电器共用一个插线板的话，在这些电器启动的时候，供给电脑的电压就会受到很大的影响，往往就表现为系统重启。 解决办法就是把他们的供电线路分开。 2(强磁干扰 不要小看电磁干扰，许多时候我们的电脑死机和重启也是因为干扰造成的，这些干扰既有来自机箱内部CPU风扇、机箱风扇、显卡风扇、显卡、主板、硬盘的干扰，也有来自外部的动力线，变频空调甚至汽车等大型设备的干扰。如果我们主机的搞干扰性能差或屏蔽不良，就会出现主机意外重启或频繁死机的现象。 3、交流供电线路接错 有的用户把供电线的零线直接接地(不走电度表的零线)，导致自动重启，原因是从地线引入干扰信号。 4(插排或电源插座的质量差，接触不良。 电源插座在使用一段时间后，簧片的弹性慢慢丧失，导致插头和簧片之间接触不良、电阻不断变化，电流随之起伏，系统自然会很不稳定，一旦电流达不到系统运行的最低要求，电脑就重启了。解决办法，购买质量过关的好插座。 5 , 通过您的介绍，肯定是您的显示器出了问题。有以下几种可能，1 电源板电容鼓包了滤波不好2显示器高压板不能点亮灯管3开机是如果屏幕有发红的现象和背光不均匀的情况那就是灯管的问题，建议你懂电路的话可以试修如果不懂的话去维修部检修就可以了。 Is team-oriented and team building.
