|It's some compaq junk. (You have a compaq PC or the hard drive is from a compaq?) You probably have compaq diagnostics loading on startup and the cpqdiag.386 file isn't being loaded so you're getting that message.|
Start up the computer. Before the OS starts to load, start tapping F8. Choose 'command prompt only' from the menu that comes up. At the c:\> prompt
type edit c:\windows\system.ini and enter. The edit screen will come up with the system.ini file. Locate the [386 Enh] section and using the arrow keys place the cursor in that section and on a new line type in the command as the error message words it.
Then hit ALT to highlight the FILE section of the edit taskbar. Hit ENTER to open it and S to save the new file. The hit ALT again, ENTER again and X to exit. You should be back at the c:\> prompt. Then do a CTRL-ALT-DEL to reboot the computer and let it boot to normal mode and see if it goes OK
