completely resolution steps.

4. Reasons and Resolution tips
Here are some resolutions steps that you can follow if
are sure that the blank screen problem is NOT due to a
booting problem.
Unserviceable Monitor?
One of the most common causes of this blank screen is
due to an unserviceable monitor. So replace it and
restart your computer to find out whether the problem
is resolved.

5. Reasons and Resolution tips
Monitor off?
 You might also get a blank screen if you forget to
switch on the monitor itself.
 Yes, this is a silly reason, but some people indeed
forget to turn on their monitors and think that
something has really gone wrong with their
computers.
 So just recheck whether you have indeed turned on
your monitor.

6. Reasons and Resolution tips
Cable unplugged?
Check that the monitor plug is firmly plugged in to the socket of the
CPU. This is the most common reason for getting a blank screen.
Processor Overheated?
 An overheated microprocessor can also cause a blank screen; blame
it on the inefficient CPU fan.
 So in order to get around this problem, you can follow any of these 3
steps. Before that just touch your microprocessor and see if it is
heated up.
 If so, then 1) Keep your computer room cool by installing an air
conditioner or extra fans. 2) Provide additional CPU fan or
processor fan for your computer 3) lastly, switch off your computer
for about 15 to 20 minutes and restart it to see if the problem is
resolved.

7. Reasons and Resolution tips
Installed anything?
 A newly installed hardware component can also
cause this problem.
 The drivers of the newly installed hardware part
might have damaged the critical system files of your
computer resulting in a blank screen.
 So try uninstalling that hardware part and restart the
computer to see if the monitor has started
displaying.

8. Reasons and Resolution tips
Graphics card damaged?
 A damaged graphics card in your computer can also
cause a blank screen.
 If you are well versed with handling the hardware
parts, then you can go ahead and replace it,
otherwise it’s better to call up an experienced
technician for help.
 If your computer is still under warranty, then you
can ask an authorized dealer to do that for you.
 Once the replacement is done, restart your computer
to see if the problem has been resolved.

9. Reasons and Resolution tips
Got a corrupted OS?
 A corrupted operating system (OS) can also prevent
your computer monitoring from displaying anything.
 If you have the installation CD for the OS, you can
try repairing it or do a complete reinstall of it and
check if the problem is resolved.

10. Reasons and Resolution tips
Hard disk damaged?
 A damaged hard drive is another major reason for
getting a blank screen.
 So try replacing it and check if the monitor gets back
to normalcy.

11. Reasons and Resolution tips
Mother board gone?
 If something more serious has happened to your
computer, namely, if the motherboard had a short
circuit, it can result in a complete system damage
including a blank screen.
 So you need to replace it and check if the problem
has been fixed.

12. Conclusion
 If your computer monitor still remains blank despite following
all the above steps, then there is a greater possibility of a
serious damage happened to your computer.
 In such a situation, it is better to seek the help of a trained
computer technician near you.
