Turned on computer one morning after using it the night before and received the message "windows\system32\config\system file missing or corrupt. Use original CD to repair." Tried, and the computer would not read the CD. Spent an hour talking to Dell, and did not solve anything. I am using Dimension with Windows XP Pro Media Center Edition. Tried to run in safe mode, had a list of files such as ntoskml.exe, hal.ldd, kdcom.dll, bootvid.dll, config\system. and config\system.alt. still did not work. Help!
