Windows - Fatal Exception Illegal Operation

Fatal Windows Exceptions Illegal Operation

So what causes events like fatal exception errors? When a program "crashes," it means that something has gone seriously wrong during the program's execution (often called a 'bug'). The operating system will respond to the problem and (attempts) kills off the offending application. Then, the operating system report something cryptic like "fatal exception error" (along with a collection of hexadecimal numbers). Nearly all these exception errors are caused by human error on the part of a programmer. Good code testing methods finds many errors, but usually it does not find them all. This where the operating system attempts to handle the problem and report some error.

An operating system (Windows) keeps a log of the information related to the error for the user to view the details and determine possible causes of the fatal error. Similarly, in some cases the image of a process (core dump) is also sometimes maintained by the Windows OS in the event of a fatal error.

Fatal Windows errors

Fatal exception errors are returned by a program in the following events:

  • An illegal instruction has been encountered
  • Invalid data or code has been accessed
  • The privilege level of an operation is invalid
  • A program attempts to divide by zero (at least for integers)

When any of these cases occurs, the processor returns an exception (error report) to the operating system, which in turn is handled as a fatal exception error. In many cases the exception is non-recoverable and the system must either be restarted or shut down, depending upon the severity of the error.

Not enough memory to render page:

This error appears when a document you sent to the printer is too big for the printer’s buffer memory. Try reducing the size of the print job.

Data Error Reading/Writing Drive C: (or other drive):

The error messages given indicate hard drive failure or serious data corruption (FATAL)
This error can be caused by:

  • Hard drive not setup properly in CMOS / BIOS.
  • Hard drive not physically connected.
  • Damaged hard drive (hard drive corrupt or bad sectors).

This program has performed an illegal operation and will be shut down. If the problem persists, contact the program vendor:

A running program tried to communicate with the computer’s CPU, which failed to understand the program's request or the request would have resulted in a compromised state or action. This usually indicates a problem with the given program. You can see if there is a updated program available. See if the program vendor offers a website link for support and updates.

There is not enough free memory to run this program. Quit one or more programs, and then try again:

You do not have enough FREE SYSTEM memory run program. You are likely to be losing precious system resources through Spyware processes, or possibly other memory hungry tasks.

There was an internal error, and one of the windows you were using will be closed. It is recommended that you save your work, close all programs, and then restart your computer:

You most often see this when you open several windows from the same application, such as many open browser windows or several text documents running in separate windows. When one of the open windows experiences errors and crashes, this message pops up.

Invalid system disk Replace the disk, and then press any key:

That message means that your hard drive is no longer found to have a valid boot image. Likely causes are a defective drive, corrupted System Boot files, or a corrupted boot sector. This is best recovered by a skilled Technician.

Not enough memory to render page:

The printer driver may have determined the amount of printer memory incorrectly. This behavior can also occur if the printer does not have enough memory to render the page.

Stop 0x0000000A or IRQL_NOT_LESS_OR_EQUAL:

This behavior can occur if there is incompatible hardware or an incompatible device driver on your computer. Try and restore your configuration using the Last Known Good Configuration option from Safe Mode. Remove any newly installed hardware.

Invalid Page Faults:

  • An unexpected event has occurred in Windows (unknown error).
  • A program has requested data that is not currently in virtual memory, and Windows attempts to retrieve the data from a storage device and load it into RAM (memory).
    An invalid page fault error message can occur when Windows cannot locate the data.
  • The virtual memory system has become unstable because of a shortage of RAM or disk space.
  • A program is attempting to access data that is being modified by another program that is also running (conflict).

Windows Protection Error:

This behavior can occur when a when your computer loads or unloads a virtual device driver (VxD). It is often related to a invalid hard disk or CD-ROM device driver (or several device drivers installed for the hard drive).

Non-system disk or disk error. Replace and press any key when ready:

You may see this message if your floppy disk drive, hard disk drive, or CD-ROM drive does not contain boot files or a valid boot partition.

Fatal error: An error has been encountered that prevents setup from continuing:

One of the components that Windows needs to continue setup could not be installed.
You may see this message if your hard disk is damaged or corrupted. You receive the error messages because the Setup program is trying to repair the problem on your hard disk.

System has recovered from a serious error:

This problem occurs because after a Minidump file is written, the paging file continues to set a flag set that indicates that a Minidump file must again be written (multiple write attempts).

The system is low on virtual memory. Windows is increasing the size of your virtual memory paging file:

This issue may occur if there is not sufficient memory on the computer, and when the current virtual memory settings are set too low. One simple correction is to increase your allocated Virtual Memory size. Normally Windows XP will do this correction for you.

This application requires the Windows Installer to run:

The Windows Installer is missing or damaged. For Windows 2000 and XP download the latest version from this Microsoft link Windows Installer 3.1 Download (outside this site)

Internet Explorer. A runtime error has occurred. Do you wish to debug:

Internet Explorer is displaying this message because it has encountered this error when trying to run some JavaScript on the page. Try removing and updating Java (outside this site).

The margins of section X are set outside the printable area of the page. Do you want to continue?

Your margins are set closer to the edge of the paper than your printer is capable of printing. Reduce the margins in the program you are printing from.

Summary - what can you do?

An illegal operation often means a bug in the application program (or sometimes in the Windows operating system) or it may be the result of a combination of unusual circumstances that the program and operating system could or did not anticipate. In the latter case, the problem may not be repeated and is (very) intermittent.

A reasonable practice if you get an illegal operation message is to continue working if the application is still running, or to restart the program if it has been terminated, and, if the problem recurs, to reboot the operating system and try again. If you continue to experience illegal operation errors with an specific application, then report the problem to the software vendor.
