Software Problems
If you are having trouble with an applicaton program, try the
following solutions:
1.
2.
3.
4.
5.
6.
If the application program does not start, check that you are
following the correct procedure for starting the program, and
that it is installed correctly. If the program is stored in a
directory on the hard disk drive, make sure you are working
in or specifying the corrct directory. If you are using a
program on a diskette, make sure have inserted the
correct diskette in the correct drive.
Your computer can run at either high speed or low speed.
while almost all programs work properly at the faster speed,
some must run at the slower speed. Check your software
manual to see if this is the case, and change the CPU speed if
necessary. See "Changing the CPU Speed" in Chapter 2 for
instructions.
If you have entered an MS-DOS command that you want to
stop, try pressing the following key combinations:
Ctrl C
Ctrl Break.
An application program can occasionally lock up the computer
making it unresponsive to the keyboard. If your computer
does not respond when you type on the keyboard, you can
press Ctrl Alt Delete to reset it.
If resetting the computer doesn't help, turn off your system,
wait five seconds, and then turn it back on. Then you can
restart your application program.
If none of these solutions solve your software problem, contact
the woftware manufacturer for technical support.
