The IT support department of antivirus company MYSecurityCenter
conducted research on the most common computer issues suffered by
British home users in 2012. Below are the top 10 most common PC
problems, and some tips on solving - or even preventing - them from
security expert Janus Rægaard Nielsen.
1: My computer is slow
The most common problem of all. A slow computer can cause many
frustrations, but fortunately there is something you can do yourself
before you replace it. There may be several reasons for a slow computer;
however, the most common is lack of maintenance. Fragmented data, a
corrupted registry, spyware and dozens of unnecessary programs running
at the same time, easily eat at the speed and performance of your PC.
Tips: Keep track of your programs. Remove those of which you never
use or shut them down when you've used them. Clean your registry with
one of the many free or paid applications available for Windows. These
two initiatives alone will easily be able to make your PC up to 30%
faster. Also, run Disk Defragmenter and stop unwanted programs starting
with Windows by running MSconfig: see our guide on How to make your Windows PC boot faster
2: My computer freezes
Also a common problem, but it is far more serious than a slow PC. In
most cases it is caused by viruses, especially spyware that has been
installed on your computer. It can enter via a click on a link to a fake
website from an email or so on. Often the email is being sent from what
looks like your bank, Paypal, Facebook or similar. Last year
MYSecurityCenter registered an increase in malware infections coming
from Facebook-related fraudsters among their customers.
The problem can also be caused by hardware - perhaps some memory you
just installed - or recent software updates, including Windows Update.
Tips: Check the link you are clicking by holding the cursor over it
to see the link's full address. Does it look suspicious? Never give out
your passwords or credit card information to anyone, even if it seems
like your bank requires you to verify your account. It's a clever
phishing trick that hackers use to gain access to your money. Make sure
your antivirus and anti-spyware software is updated. Most antivirus
programs can be set to automatically to check for new updates. If you
are sure that your computer is spyware free, the problem may be due to
outdated hardware drivers. Check your hardware drivers for updated
versions. Outdated drivers can cause your computer to stop responding
and freeze.
If
you suspect the problem is hardware related, you can try uninstalling
any component you recently installed, or try removing or unplugging
unnecessary hardware one piece at a time then booting your PC to see if
the problem goes away. You can also try using Windows Restore to roll
back to a previous restore point.
3: I forgot to backup my data
Unfortunately, backup is still an overlooked security task for many
home users - until the day it is too late. Important documents, photos,
music libraries and emails are automatically stored on your computer's
hard drive, which is a mechanical and electrical device. When it breaks
down (and it is
when, not if) this data will disappear forever.
Even if you have a warranty from the hard drive manufacturer, it does
not cover your data, it only replaces the hard drive with a new one.
Tips: Find a solution that automatically makes backup to an external
hard drive, server or cloud service. If you choose to back up to a hard
drive, make sure that it is not placed near your computer as in case of
fire it will also be destroyed. Backup should preferably be an automated
process that operates independently of whether you remember it or not.
Online backup solutions have the advantage that you can access your data
from anywhere in the world. They are not affected by natural disasters,
and most online services guarantees 100% security by providing backup
to their backup.
4: I get bombarded with adware and my home page has changed
Many do not notice that they often accept a new toolbar when they
download free programs such as Adobe Reader. For example Adobe Reader
now offers the Google Chrome internet browser as part of its download.
Whilst Adobe and Google are reputable companies, other free downloads
may install toolbars or other applications that can contain malicious
code that hijacks your browser and changes all the settings. So your
home page for example is changed to another website that you can't then
change back. At the same time, annoying pop-up messages with
advertisements for products you've never asked for are constantly
displayed on screen every time you try to browse the internet.
Tips: Read the conditions before downloading a new program and pay
attention to what you allow. If damage is done, it can be difficult to
remove the program. The best bet is to follow the instructions found
when looking for information about the specific problem on Google. There
are probably others who have had the same challenge and have described
the solution on the internet. If you are not so technical, professional
PC support may be the solution.
5: I cannot get online
Internet
connection problems can be caused by many different things. The most
common are network misconfigurations, hardware or software errors in the
router, latency from your Internet Service Provider, incorrect IP
address configuration, incorrect connection of network cables, firewall
applications that block http traffic from your PC or temporary timeouts
your ISP.
Tips: Check that the Wi-Fi is enabled on your computer - laptops
often have a button, switch or Function key combination somewhere on
your computer or keyboard. Check that the network icon on your computer
is connected or if there is a yellow warning signal or it is disabled.
If it is connected, call your network provider or get hold on someone
with more knowledge on IT.
If Wi-Fi is disabled, you must check whether the cable is connected
properly or if wifi is not on. If there is a yellow warning, you must
reboot the router. If this does not work, try pressing Start in Windows
XP, Vista or 7 and typing "cmd" into the search box and click enter.
Then a black box pops up where you can type "ipconfig / release" then
"ipconfig / renew". If the internet is not working now, call your ISP.
6: My computer turns off by itself
Typically this is due to dying power supply, bad cable connections,
defective battery or overheating when the computer shuts down by itself
to cool down.
Tips: Check first of all that the cables are properly connected. If
the computer is very hot, check if the fan needs cleaning of dust. If it
is a laptop, check whether your battery has deteriorated over time and
may need to be replaced.
7: My smartphone will not synch with my PC
In order to ensure backup of your smartphone, it is important that
you regularly synch your phone content with your computer. When
synchronisation does not work as expected may be due to various factors,
depending on the type of smartphone and PC. Sometimes it is required
that all programs are closed, during synching or backup.
Tips:
Close open applications, if required. Be sure to download or reject the
proposed updates that pop up along the way, so synchronization can be
done. Look for the icon of synchronization to appear and check if for
example the latest photos on your smartphone have been transferred to
the computer. Verify the user manual for your device.
8: My wireless network is unstable
An unstable wireless network is a very common problem. It can be
caused by everything from radio waves that interfere with the signal to
the router's location in the home or outdated network drivers.
Tips: If you suspect that it may be your cordless phone, the electric
garage door opener or your radio that interferes with the wireless
connection, it may be an idea to change the radio wifi settings or to
move your router. The latter can also be a solution if you have trouble
going online around the house or in the garden. You can also buy a
wireless repeater to extend the signal. Also make sure that your network
driver is always up to date.
9: I cannot print from the web
Most of us have had the need to print tickets or documents that we
ordered or downloaded from the web. If your computer's pop-up blocker is
turned on, this can cause you to not be able to print. There are also
PDF documents that are rights protected by passwords and therefore not
printable.
Tips: Allow temporary pop-ups. You can find legitimate programs that
can break the code in a protected PDF document, but they are usually
only legal to use if you or your workplace have the copyright to the
document.
10: My computer makes strange noises
If
your computer suddenly starts to buzz or vibrate, it can be due to a
hardware failure. High, whining noises may indicate problems with the
electrical components, while buzzing noises are often caused by lack of
ventilation.
Tip: Clean the filter and fan for dust and make sure that all air
inlets are free. If you have a laptop, you can try to uninstall and
reinstall your sound drivers. If it is a desktop, it may be that the
sound card needs replacement.
