If you are reading this you probably are experiencing one of
those annoying crashes that forces to make u hit the
‘restart’ button on your CPU but instead of hitting the restart button there
are a lot of things that you can do to prevent these annoying crashes and
hangs. First of all let us look into what a crash or hang really means.
A crash occurs when a program exits an application unexpectedly
after encountering an error . Mostly
after these crashes occur the Windows provides an error report with details of the Error.
HANG
Hang is a situation in which the computer encounters an
error in a program and completely or temperely stops responding to the inputs
of the user,this types of errors can make you hit the restart button, which is pretty
annoying !
CAUSES
Now let us see how
these crashes and hangs are caused.
There are two major causes of crashes and hangs
1) Software
errors 2) Hardware malfunctions.
1) SOFTWARE ERRORS
Almost 70% of all the crashes are caused because of software
bugs and in this 50% are caused due to viruses.
Viruses and worms are the major causes of crashes and
hangs, they inter-fear with he normal functioning of any application and hence
cause a huge amount of crashes and hangs.
When we open an application the computer compiles the
thousands of lines of program code to make the program do what it is meant to,when
there are some execution errors in this programs the compiler exits or hangs
during execution thus causing a hang or a crash .
For example: Several years ago the well known Swedish aeronautical company SAAB lost almost 8 JAS 39
fighter aircraft which costs almost $40million due to a bug in the
program for its flight control software, which caused its on-board computer to
hang.
2) HARDWARE MALFUNCTION
Some crashes and hangs can also be caused hardware
malfunctions which cause the computer to not work normally.
There are many causes namely overheating, dying motherboard ,faulty
ram, graphics card ,hard disk failures or file corruptions, Power Supply(PSU) of the computer providing inaccurate DC voltages etc..
Overheating during CPU and GPU intensive applications
like computer gaming can cause a lot of nasty crashes
Faulty graphics card can be easily detected if there is
a presence of coloured or black lines or dots randomly appearing on the monitor. These types of malfunctions with the graphics card can cause crashes.
Data corruption is also a major cause of crashes as it
makes data unreadable by the computer causing fatal errors.
A power supply unit (PSU) is like the heart of the
computer. It must provide the right amount of dc voltages to all the components
in order to make all the components to function properly
All the voltages namely +12v, +5v & +3.3v must be within ATX specifications. These levels can be checked in the bios.
PREVENTIVE MEASURES
1. A good antivirus software must be employed and a full
scan must be done atleast in every week.
2. If program bugs causes crashes the program must be
reinstalled or a new program from a verified source must be used.
3. The temperatures of the components must be constantly monitored. Usually for the graphics card a temperature more than 85"C is usually
considered high but may depend upon the manufacturer. The cooling fans must be
clear of dust and must be verified whether it is running.
4. The PSU voltages must be constantly monitored to prevent
loss of data and hence leading to crashes.
