How to fix illegal operations on a computer

[html] When the operating system or computer processor
receives an instruction from a program that it does not
recognize and cannot process, it may issue a
command known as an Illegal Operation. Below are reasons why
an Illegal Operation happens on a computer.<p> <img

<p>
<font color='blue'><b>TSR's or third-party
programs</b></font> <p>TSR's or third-party programs running in
the background are one of the more commonly found reasons
for Illegal Operations. If the Illegal Operation
is happening when running a game or program close all
other open programs and TSR's running in the background.
<p>If after removing these programs you no longer receive
the Illegal Operation messages, we recommend that you reboot
the computer. Once it's up, disable or End Task each program or
TSR one at a time to determine which program is causing
the Illegal Operation. <p> <font color='blue'><b>Error in
program coding</b></font><p>Verify that the program causing the
Illegal Operations is compatible with your version of
Windows and check with the developer to make sure no patches
or updates are available. There is no such thing as
a perfect software program, and it is not uncommon for
multiple patches and updates to be released during a
program's life cycle. <p> <font color='blue'><b>Data is not
being read properly from source</b></font> <p>When running a
program or game from a CD you receive an Illegal Operation,
verify that the CD is clean. Additional information on
how to clean a CD or CD-ROM drive can be found on our
Cleaning Page. <p>If you are running a game from a
floppy diskette or other drive make sure the disk or
drive does not have physical errors with it by running a
ScanDisk. <p> <font color='blue'><b>Installing a program or game
on a hard drive that has errors or is highly
fragmented</b></font> <p>Make sure that drive is not fragmented
or corrupt by running ScanDisk and Defrag on the drive.
<p>If errors exist on the hard drive, they cause the program
or game to run improperly and can cause
Illegal Operations. <p><font color='blue'><b>Corrupt
files</b></font> <p>Corrupt, bad, or missing files can cause
Illegal Operations. Try uninstalling and then reinstalling the
program causing the Illegal Operation to verify that any
corrupt, bad or missing files are replaced or
repaired during the reinstallation. <p> <font
color='blue'><b>Memory managers</b></font> <p>If you are running
a memory manager, it is recommended you temporarily disable
or uninstall this program to verify it is not causing
the Illegal Operations. <p> <font color='blue'><b>Bad,
incorrect, or outdated video drivers</b></font> <p>Bad,
incorrect, or outdated video drivers can cause Illegal
Operations when moving the mouse, highlighting, or when
high demands are placed onto the video card. Try
decreasing the resolution to make sure your current settings are
not causing the problem. <p>If after adjusting the video
settings you still encounter the same issue, verify
the computer is utilizing the latest video card drivers
by visiting our computer video drivers section . <p> <font
color='blue'><b>Computer virus</b></font> <p>Because computer
viruses and other malware load into memory and can improperly
modify files they can cause Illegal Operation error
messages. Make sure an anti-virus protection utility is
installed on the computer and that it is up- to-date.<p>
 <font color='blue'><b>Added hardware</b></font> <p>If new
hardware has been recently installed (e.g. computer memory) in
the computer it or any drivers that had to be installed
may be conflicting with other computer hardware. Temporarily
remove any new hardware and the software associated with
it to make sure it is not causing the problem. <p><font
color='blue'><b>Bad Memory, invalid bits or physically bad
memory</b></font> <p>Bad memory can cause Illegal Operations. If
you have recently added memory to the computer, remove the
memory to make sure it is not causing the problem. If
no memory has been recently added and you have tried all
the above recommendations, test your computer
memory. <p> <font color='blue'><b>Corruption or problem
within Windows</b></font> <p>Because Windows controls the
memory operations and all system operations if any part
of Windows is corrupt it can cause Illegal Operations. If
you have tried all the above suggestions, we suggest
reinstalling Windows.[/html]
