General Protection
Fault Errors in Windows 3.x

There are several possible solutions to General Protection Faults Unrecoverable Application Errors.

First solution:

Windows and many Windows applications create temporary files on your computer's hard disk drive. Sometimes these files become damaged, or for one reason or another, are not deleted when the program is done using them. This often occurs if you turn off your computer without properly exiting Windows. To ensure that damaged or unnecessary temporary files do not become a problem, you should routinely delete Windows 3.X temporary files.

Note: You must delete these temporary files from DOS without Windows running.

In your C:\Windows and C:\Windows\System directories, delete all *.tmp files by entering the del *.tmp command at the DOS prompt. At the DOS prompt, type set, and press the ENTER key. Note the subdirectory identified in the line TEMP=. Go to that directory, and also enter the del *.tmp command to delete temporary files.

Second solution:

Check for errors on your hard disk. At the DOS prompt, type the chkdsk /f command and press the ENTER key.

Note: See your DOS manual for more information and usage of the del command and the chkdsk utility. If you are using a disk compression program like Stacker, SuperStor or Doublespace, check the compression program user's manual to see if using CHKDSK is suitable or if there is a specific program you should use with the compression program.

If steps 1 and 2 above do not correct the problem, there may be a conflict between Windows and another program. Edit your autoexec.bat and configsys files to remove any TSR (terminate-and-stay-resident) programs, and see if the General Protection Faults or Unrecoverable Application Errors still exists. If it does not, add line by line until it does. You will then know which program is conflicting. If the problem persists after removing all TSR programs, then use a standard setup in Windows. Change the [BOOT] section of the system.ini file to be similar to the following:

    shell=progman.exe
    mouse.drv=mouse.drv
    sound.drv=mmsound.drv
    comm.drv=comm.drv
    keyboard.drv=keyboard.drv
    system.drv=system.drv
    display.drv=vga.drv (or ega.drv, cga.drv, etc.)

To temporarily change a setting in the system.ini file, you can add a semicolon (;) at the beginning of the line to denote a commented line.

For example:

    ;display.drv=mgraf.drv (This line is commented)
    display.drv=vga.drv
    (This line is active)

To change the setting back, remove the semicolon and delete the line you added in.

When testing, you should also make sure the LOAD= and RUN= lines, in the win.ini file are blank, and that the Windows Start Up group is empty.
