I'm on an older computer with Windows 2000 which has been working fine. Today, in the middle of doing nothing out of the ordinary, I got a blank screen. So I rebooted and was served up this error message: Windows could not start because the following file is missing or corrupt: \WINDOWS\SYSTEM32\CONFIG\SYSTEM You can attempt to repair this file by starting Windows Setup using the original Setup CD-ROM. Select 'r' at the first screen to start repair. I don't have the Setup disc but I do have the original program disc - but it wouldn't read it and keeps giving me the same error. I can't even start is Safe Mode. Any ideas?
