昨晚我正常关闭电脑。
今天我登录时花了比平常更长的时间，我收到了这个错误。
C:\windows\system32\config\systemprofile\desktop refers to a location that is unavailable. It could be on a hard drive on this computer.or on a network. Check to make sure that the disk is properly inserted, or that you are connected to the Internet or your network and then try again. If it still cannot be located the information might have been moved to a different location.
屏幕看起来像一个旧的win2000主题，屏幕上的所有图标都是空白的，开始菜单中没有程序。
我该如何解决？
