Control-Alt-Delete Does Not Work

Microsoft Windows 98

The Control-Alt-Delete sequence has no effect on my computer. When it
freezes I have to turn it off, then on and wait for it to check the hard
drives before booting.
Click Start>Run, type: system.ini and click OK.
Look under the [386Enh] section heading.
If it contains the entry "LocalReboot=Off" or "False", change it to "LocalReboot=On"
or "True".
If it does not contain the entry, add it.
Click File menu>Save, then Exit.
