I have a lot of errors that say source: disk category:none Event:7 user:N/A under the system log. There are also some DCOM errors and some service control manager erros all under the system log.
As for the application log there are 2 VSS source errors 2 EventSystem errors one apacheservices error and one nview_info error
right click your harddrive icon, go to properties, tools, error checking, put a check in both boxes, ok, it will tell you that it can run but it will run on next boot, click yes and reboot and let it run
