白天都好,到了晚上,,饿滴个神啊..救救我吧

网络不稳定，时好时坏

但勉强还能打开网页

如果是共享上网，可能是别人抢了你的带宽
如果是个人上网，原因有多种，可能性最大的就是该网站有问题

首先查杀下病毒、木马，看看是不是这些在作怪。如果不是那就看优化了。 如果版主不愿重装和升级硬件的话，那么就尽量在软件和系统上下功夫,而在优化上，比较有名的是优化大师和超级兔子版主可以试试。 1、不要加载太多随机启动程序 (提高开机速度必须做的) 不要在开机时载入太多不必要的随机启动程序。选择“开始→程序→附件→系统工具→系统信息→系统信息对话框”，然后，选择“工具→系统配置实用程序→启动”，只需要ctfmon杀毒、查木马的程序前打上钩，其他项都可以不需要，选中后确定重起即可。 (笔记本还须在笔记本程序上打钩) 2、不要轻易使用背景 不要使用ActiveDesktop，否则系统运行速度会因此减慢(右击屏幕→寻显示器属性→Web标签→将其中关于“活动桌面”和“频道”的选项全部取消)。 3、设置虚拟内存 自己设定虚拟内存为机器内存的3倍，例如：有32M的内存就设虚拟内存为96M，且最大值和最小值都一样(此设定可通过“控制面板→系统→性能→虚拟内存”来设置)。 4、一些优化设置 a、到控制面板中，选择“系统→性能→ 文件系统”。将硬盘标签的“计算机主要用途”改为网络服务器，“预读式优化"调到全速。 b、将“软盘”标签中“每次启动就搜寻新的软驱”取消。 c、CD-ROM中的“追加高速缓存”调至最大，访问方式选四倍速或更快的CD-ROM。 5、定期对系统进行整理 定期使用下列工具：磁盘扫描、磁盘清理、碎片整理、系统文件检查器(ASD) 6.取消不必要的服务。Windows XP调用了许多用户可能根本用不到的服务，这些服务不仅影响运行速度，对保护系统安全也非常不利。因此，可以根据需要禁用不必要的系统服务。方法 ：选择"开始"菜单里的"运行"，输入"Services.msc"打开"服务管理控制台"，通过更改服务的启动类型启动或停止该项服务。 7.如果感觉Windows的单窗口浏览器速度比较慢，可以加以改进，方法是 ：打开"我的电脑"，点击"工具"->"文件夹选项"->"查看"，选中"使用独立的进程打开文件夹窗口"。这样可以防止一个较慢的设备影响用户界面的响应速度。
