Having a slow
computer is not something most users fancy, but that is what most of us
end up with after prolonged usage despite having the latest hardware.
Understandably, there are also a few of us who are trapped with a
low-end PC and are forced to get as much out of it as possible. This
article caters to both these type of users as it not only explains how
to make your computer as fast as it was when new but also how to reduce
the footprint of your system to utilize your PC's current system
resources in the best possible way.
First thing first. Make sure your PC isn't infected by a virus, worm or other malware
Anyone who has
used an infected computer
will verify how painfully slow a computer becomes when infected by a
virus. More tech savvy users will counter that an infected computer's
speed depends upon the type of malware. To be honest, it does. However,
based on my personal experience, I can say that while some malware are
designed specifically for making computers slow and unresponsive, most
malwares tend to decrease a computer's performance.
If your computer is infected, the first thing you need to do is deep
scan your entire hard drive to remove all traces of the virus. Also,
scan your secondary storage devices to make sure that they are clean as
well. Additionally, make sure to follow
best security practices to avoid getting infected in the future.
Remove unused and unnecessary programs
Now that we are sure that
your computer is not slow because of a virus, you need to get rid of
all the unnecessary programs that you have installed on your PC. To
remove these programs, go to
Programs in the
Control Panel and uninstall your unnecessary programs one by one. If you are like most Windows users (
including me)
and are having a tough time figuring out which programs to uninstall as
all of them seem important, follow this rule: If you have not used the
program in the last month, it probably is unnecessary. It is better to
uninstall that program given that you can reinstall it whenever
required. It also is a good idea to remove all the useless software that
came bundled with your computer. If you want, you can remove unused
Windows features as well to further tone down your operating system.
Try faster alternatives to your everyday programs
If you use
applications that require too much computing power to operate, you are
better off replacing them with applications that do the same job as them
but faster. Few resource hogging applications that you can replace
are:-
1) Most resource intensive antivirus software can be replaced with the lightweight
Microsoft Security Essentials.
2) Microsoft Office can be replaced with
OpenOffice, an open source alternative that also has loads of amazing additions.
3) Adobe Reader can be replaced with
the free Foxit Reader.
4) The newer versions of Internet Explorer (IE 10 and above) are less
resource intensive. If you have been using an older version, it is time
to upgrade IE or replace it with
either Mozilla Firefox or Google Chrome. This will also give you faster internet speeds.
Remove unnecessary startup programs
Startup programs are the
programs which start automatically each time a user logs on. Not only do
they result in a slow startup, but they also run persistently, until
you close them manually, continuously consuming valuable system
resources (CPU and RAM) while they are running. So, disabling
unnecessary startup items results in both a faster startup and a more
responsive computer, as these applications not running continuously
means more RAM and CPU will be available for the operations you perform
on the computer.
To disable unnecessary startup programs, type
msconfig in the search bar in Start menu (in
Windows 10,
Windows 7 and Windows Vista) and on the Start screen in
Windows 8 and
8.1. On Windows XP, type this in the
Run dialog box. This will start the
System Configuration utility. Click on the
Startup tab
and disable all the applications that you think are not essential on
your computer's startup. Restart your computer to see the changes. Keep
in mind to not disable your security products as that will make your
computer more susceptible to getting infected.
Restart your computer often
This
is assuming that you continuously use your computer for long periods of
time. Each time when you close a running program in Windows. it frees
the memory that the program was occupying. However, it may so happen
that some parts of the memory do not get freed which results in less
system resources available to you to use which ultimately results in a
slower PC. When you restart your computer, these occupied spaces in the
memory get freed. Although, this memory issue has been somewhat fixed in
recent versions of Windows, it still is a good idea to reboot your
computer at least once a day.
Check your hard drive for errors
Over time, as you use your
computer, chances are that some errors might creep in your hard disk
which negatively affect your computer's performance. The best way to
solve this issue is by using the inbuilt
Disk Check utility available in all versions of Windows. To use it, execute
chkdsk /r in the
Command Prompt. Remember to open the Command Prompt as an administrator. It might prompt you to restart your computer. Execute
Y to restart your PC. The
chkdsk/ r
command scans your computer's hard drive for errors and recovers
readable data. Depending upon the size of your hard disk, this step
might take some time. This step might increase your computer's
performance phenomenally if there are a lot of errors on your hard
drive.
Make sure you have enough free space
System speed is not only
dependant upon CPU and RAM. If your hard drive is above 95% full, you
will notice that your system hasn't been running at the fastest speed.
This happens because Windows require empty space for swap files to
increase in size and also as space for temporary files. It is imperative
that the more cluttered and filled a hard drive is, the more difficult
it is to read. To solve this issue, delete unnecessary data or move it
to external storage devices.
Repair protected Windows system files
As you use your computer,
it is possible that one or more system files get damaged or get
corrupted which might effect your system's performance in a negative
way. Thus, it is important to check that all your system files are
original and behaving as they should. The best way to check your
operating system's files is through the
System File Checker. To run the System File Checker, open Command Prompt as an Administrator and execute
sfc /scannow.
This command will check all your system files and if it finds that some
of them are modified or corrupt, it will replace them with the
original. This step can take anywhere between 5 to 15 minutes but is one
that you should perform especially if your system has ever been
infected by a virus.
Disable unnecessary visual effects
The
visual effects that make your computer look beautiful also slow it down
considerably. So, if you want to get the best performance out of your
computer, you should disable all these visual effects. To disable these
visual effects:-
1) Press
Windows Key+R to launch the
Run dialog box.
2) Execute
sysdm.cpl.
3) Go to the
Advanced tab in the following Window and click on
Settings in the
Performance section.
4) Then encircle
Adjust for best performance. If you want to use visual styles and themes, check it (located at the very end of the list).
5) Click on
Apply to apply the changes.
Disabling these visual effects could lead to a considerable improvement
in your system's performance especially if you are on Windows 7 or
Windows Vista and using the Aero interface without a graphic card.
Do not run multiple antivirus programs
Make sure that no more
than one antivirus program is running on your PC. An antivirus's
resident protection takes a lot of resources. So, having more than one
antivirus program would bring about a significant reduction in your
computer's speed.
Disable sound schemes
Whenever you perform an action in Windows,
a sound is played to indicate it. Although it leads to a better user
experience, it also contributes towards slowing your PC down. To make
your PC a lean work machine, you should disable these sounds. To disable
these, open
Sounds from the
Control Panel or alternately type
mmsys.cpl in the Run dialog box. Go to the
Sound tab and select "No Sounds" from the
Sounds scheme dropdown list and click Apply.
Update Windows and make sure that you are using the latest drivers for your hardware
Having
all the updates ensures that your computer is running the best possible
version of your operating system and your hardware is being utilized by
the best possible code. Also, an updated operating system makes you
more secure against future intrusions by performance reducing malware.
Use a Registry Cleaner to keep your Registry in good shape
The
Windows Registry
is a place which keeps information about all installed programs and
active system files on your system. Over time, as you install and
uninstall programs, the Registry can get filled with useless entries
which might increase its size making it difficult to read. This happens
because most uninstallers don't remove the program's Registry entries
during an uninstall. Also, the larger the Registry is on your computer,
the more time Windows will take to start.
To solve this issue, use any free Registry cleaner to remove useless
entries. Depending upon the number of entries in your Registry and its
size, you might see a significant increase in your computer's
performance.
Delete Temporary Files
Temporary files are stored in your
computer as Windows operates. They are files that contain your recently
accessed files list, log files, your internet history, form history,
cookies and temporary internet files. Over time, the number of these
files increases and cleaning them becomes important. You can use
CCleaner (mentioned above) to clean them or the inbuilt
Windows Disk Cleanup utility by executing
cleanmgr.exe in the
Run dialog box. You can also schedule a disk cleanup to ensure that it happens automatically.
Disable Windows Search Indexing Service
The
Windows search indexing service scans all the files and folders on your
system and stores information about them in a database to make searches
faster. Naturally, this results in consumption of resources. If you
don't use Windows Search often or are willing to trade faster searches
for a faster computer (as you should), disable the indexing service. To
disable it, execute
services.msc in the
Run dialog box. In the work area on the right side, locate
Windows Search service and double click on it. In the following
Properties dialog box, select
Disabled
from the Startup type dropdown and click OK. Restart your computer.
Your searches will be slow but your computer will be faster than ever.
Check Device Manager to look for hardware conflicts
Open
Device Manager
to see that all the connected hardware are functioning properly. If you
find a hardware conflict, take the necessary steps to resolve it. If
the conflict cannot be resolved, disconnect the problematic hardware
until you find a solution.
Change to High Performance power scheme
If you are running your
computer on a battery and notice that it is running slow, change the
power scheme to high performance to increase system speed. Keep in mind
that it will increase the amount of power consumed by your computer. To
change the power scheme, open
Power Options from the Control
Panel. You can directly search for Power Options in Windows 7, Windows
8, Windows 8.1 and Windows 10 from the Start Screen/Menu.
Check if your computer is overheating
If your computer is
overheating, then it is possible that it is causing your computer to run
slowly. This is because most modern processors slow down when the
computer is overheated to allow the computer to cool down.
To prevent your computer from overheating, make sure that the cooling
fan works properly and that there is no dust clogging the air vents as
it will prevent air flow which will result in poor cooling. Clean your
computer's case with a light brush and place it somewhere where it can
be effectively cooled by air. If you use a laptop,
a cooling pad might be of help.
Defragment your hard drive
When Windows stores a file on your
hard drive, it does not look for a single place to store your file as a
whole. Instead, it stores the fragments of the file randomly, i.e
storing them at whatever empty space it can find the quickest. Due to
this, the fragments of a single file can be scattered all across a hard
disk. A hard drive that has many files distributed like this is called
as fragmented. Naturally, this results in slower file access times
because Windows needs to find all these pieces and put them together
(something like a jigsaw puzzle) before the file can be accessed.
This is what defragmentation corrects. When you defragment a hard drive,
the scattered pieces of a file are put together and stored on the hard
disk in continuous cells (assuming a hard disk to be made up of a large
number of cells with each cell representing a particular storage space).
To defragment your hard drive, you can use the in-built
Windows Disk Defragmenter utility. It can be searched on the
Start Screen/ Menu in Windows 10, 8 & 8.1 and is located at Start>Programs>Accessories>System Tools in older versions of Windows.
Use ReadyBoost to increase the speed of your Windows computer
If
you are running a computer that does not have enough RAM, using a flash
drive with the ReadyBoost technique can and will give you significant
improvement in speed. As with ReadyBoost, your flash drive becomes a
cache that stores files that you might immediately require giving you
faster access times than if those files had been stored on a hard disk.
Keep in mind that ReadyBoost depends upon the condition of your flash
drive and was intended to increase speeds of devices which were short on
RAM. If you already have a sufficient amount of RAM, chances are that
you might see very little to no improvement in speed by using it.
Reinstall Windows
This is one of the more drastic methods and
should only be used if all the methods mentioned above fail to bring any
significant increase in your computer's speed.
If you haven't reinstalled Windows in a really long time, it is possible
that because of constant use, the system has got bogged down with
useless clutter in a way that no amount of tweaking will fix its
condition. Then, reinstalling Windows is the only option.
Reinstalling Windows brings about a definite increase in speed but gives
you a new PC without all your software and customization. Modifying it
according to your needs will take a lot of time though but that is
something you must sacrifice for a faster PC.
If you use Windows 10, Windows 8 or Windows 8.1, you can refresh your PC
without affecting your installed apps and settings. To refresh your
Windows 8 PC, open
Update and Recovery by going to
Change PC Settings
from the Settings button that appears when you move your mouse pointer
to the right side of your screen. Windows 10 users can directly search
"Refresh" from the Start menu. Under it, click Recovery. Then under
Refresh your PC without affecting files, click
Get Started.
Upgrade to a solid state HDD
Although solid state hard drives
are a lot faster for writing and reading data than older optical hard
drives, their heavy price is something that keeps them out of the range
of many. Still, if you do manage to get one for your PC, the change in
speed will be immediately visible.
If all else fails, get more RAM
RAM or the Random Access Memory
contains all files of the currently running programs that are
immediately required by the computer. Accessing files from the RAM is
much faster than doing the same from a hard disk. This means that more
the RAM you have, more the programs you can run without compromising on
speed. RAM upgrades do not cost much and are one of the best ways to
speed up a slow computer.
