我的电脑自中了一次木马病毒以后（已经清除了），一直不正常的工作着！有如下问题，请高手帮忙解决！叩谢！机子是工作电脑，不方便重装系统！
  1.声卡不正常：开机正常驱动后，下次开机后声卡驱动就又不见了！电脑说没声频硬件！但管理器里声卡又是正常的！没有叹号！
  2.插上U盘右下角不显示图标！但可以正常使用！拆卸U盘时只能在控制面版里拆卸！
  3.文件图标显示不正常：图标的分辩率有问题！显卡正常驱动过！看图片一切正常！
下面是本机的开机日志和问题图片！请帮忙！谢谢！

早应该重新做系统

可能系统文件被病毒感染后在杀毒过程中被删除了~~~不好办
  试下在运行框中输入 sfc /scannow

记得把装系统时用的盘放进去

公司工作的电脑吖!不能随便格机的!
机子还有个问题:
按装MSN或office软件时老是出错!不能继续!!!

运行MSN或office软件是就会显示正在安装!过一会就提示出错!

另外装一套操作系统。

没好的办法，做备份吧！
