Fixing Garbled
Display Problem
(Safe, Fast and Easy).
(For DESKTOP
PC)
There are many ways on how to determine the problem of your
PC, but sometimes it’s hard to understand how to fix it safely, fast and easy.
Knowing the Beep Codes is one way to easily determine the defects of
the computer, if you knew it. Most of the expert technicians are relying on this way, specially
in the absence of the monitor or LCD. The memory has its own unique beep code
when it is defective, the VGA card has its own,
motherboard and the processor also have their own beep codes when they
are damaged.
But how about Garbled
display on your monitor? Your computer will not give out beep codes when this problem
occurs.
Causes of
the Garbled Display on your PC.
There are at least
two (2) reasons why sometime there is garbled display on your PC.
1.)
Defective VGA Card (Video Graphics Adapter Card),
mostly.
(AGP VGA Card)
(PCIE VGA Card)
2.)
Defective Memory Card or (RAM) “but this is very
seldom”.
(Memory Card)
How To Fix
Garbled Display Problem.
When this problem occurs, there is no other way but to
change the damage VGA Card or Memory Card
if it is really the problem. Isolation is the best way to determine the problem, (meaning try to test it to
another CPU with the same VGA Card or Memory slot as the one from which the
defective belongs).
Steps on How to Isolate and replace the VGA Card.
1.) First,
unplug the power cable of your CPU.
2.) Disconnect
all the connections at the back of your CPU, (the keyboard, mouse, VGA connectors and
others so that it is totally unconnected and safe from static occurrence).
3.) Open the
sidings of your CPU by unscrewing at the back of it if there’s any.
4.) Lay flat your CPU over something that is none
conductor (none metal) for you to have a full view what’s inside of it.
5.) Then you
will see the VGA Card standing inserted inside the VGA port on your
motherboard. (see picture above for
reference).
6.) Unscrew
the VGA Card if there’s any and then slowly pull it upward towards you, (it can
be easily pulled out if there is no lock underneath, but if you’re having a
hard time doing it, there may be some push or pull lock at the edge of the VGA
port that’s holding the VGA Card).
7.) After
removing, test the VGA Card into the other CPU
with the same VGA Slot as the other one from which the defective belongs,
(if there is available) if none, just bring the VGA Card to the nearest
computer store to first test it before buying
replacement. (If same problem occurs to the PC in which you have tested
the suspected VGA Card, then that really is the problem), and there is no other
way but to replace it with a new one.
8.) Then, insert
the new VGA Card inside the VGA port slowly until it reach the bottom the port,
(make sure it inserted properly).
9.) Return all
the connections at the back of the CPU in which you have disconnected, (the
mouse, keyboard, VGA Cable, and other connections to its designated place.(the last to be connected should be the power cable
for safety purpose).
10.) Then, if
all is rightfully connected, turn on your CPU.
Display will become
normal if your PC has already been fixed rightfully and no other defects
occurred. (That's it!)
