The three main types of computer failures
are system errors, freezing, and applications
quitting. Simply put, Mac system errors warn
you with the dreaded bomb Alert box. A
system error occurs when there is a conflict
between the operating system and one or
more applications, like Microsoft Word or
Internet Explorer. The next type of computer
failure is freezing, also known as crashing or
hanging. In this case, the computer locks up
and the mouse and keyboard become
useless accessories. Freezing exists both at
the individual program level and on a system
wide basis. An application suddenly quitting
is the third type of computer failure and
probably the most common. This means that
only one program is effected rather than the
whole system. All three types of computer
failures are frustrating if you do not know
what to do, but by following these steps you
will learn how to properly unfreeze your
computer.
How to restart a PC
After any common computer failure follow
these steps. Simultaneously hold down the
Control key, the Alt key, and the Delete key.
A dialogue box will ask you if you want to
exit the current program. Click the Task List
button. An End Task window appears and
lists the programs you are currently running.
Select the program you were in when your
computer froze. For instance, if you were
working with Microsoft Word, but went to
check your e-mail in Netscape, and then the
computer crashed, you would select
Netscape in the End Task window. After
selecting the correct program, hit the End
Task button. Hopefully, the program will
unlock at this point. You should then restart
your computer by going to the Start menu
and selecting Shut Down. In the Shut Down
window, click the Restart button and OK,
and the computer will reboot.
HOW TO PREVENT FUTURE FREEZES
Rebuilding your desktop, emptying your
trash, deleting excess e-mails, and
cleaning out temporary files and
histories.
System error 5 - Access is denied
This is a permission issue. If the net view
command fails with a "System error 5 has

remote computer; 5) make sure client for ms
networks is enabled on local computer; 6)
make sure you type the correct name. 7)
Make sure no firewall running or any security
setting.
VPN Case Study - Can ping VPN server but
receive System error 53 using net use
Case Study - System Error 53 - The network
path was not found.
System error 67 - The network name cannot
be found
Symptom: When using net view \\computer
or net use \\IP, you may receive above error
