Personally, I don’t see the point in upgrading your hardware if your
computer does everything you need it to. However, sometimes
it’s nice to improve what you already have. In this guide we will learn how to make the most out of the hardware you have and make Windows 7 run faster. (
Here’s a similar list for Windows XP and for
Windows Vista.)
I highly recommend you
create a system restore point before starting.
Note: There is a lot of crossover with this guide and the guide to
extend laptop battery life as some of the procedures, listed below, will help save power.
1. Scan Your PC for Malware
The first step you should take, to increase performance, is to scan for and remove malware. Use
Microsoft Security Essentials to perform this task.
For a more in-depth look at PC security, check out the
PC Security Handbook.
2. Defragment Your Hard Disk
Imagine
you are in a shopping mall, and the person you are with wants to visit
fifteen different shops. However, this person ends up walking you up and
down the mall six times. Does that make sense? Of course not – as human
beings, we like to do things to save time.
When your hard drive
becomes fragmented, it is literally wasting time by looking in all kinds
of places on the disk for all the pieces of one file. Defragmenting
your drive is a great solution to speed up your computer as it puts all
the files together in order.
- Click the Start button, type Defrag, and click Disk Defragmenter.
- Click the drives you want to defragment and click Analyze.
- Click Defragment.
If you want to schedule disk defragmentation (so you don’t have to do this manually), see this guide:
Schedule Disk Defragmentation.
3. Detect and Repair Disk Errors
Over
time, your hard disk develops bad sectors. Bad sectors slow down hard
disk performance and sometimes make data writing difficult or even
impossible. To detect and repair disk errors, Windows has a built-in
tool called the Error Checking utility. It’ll search the hard disk for
bad sectors and system errors and repair them for faster performance.
To detect and repair disk errors:
- Click the Start button and click Computer.
- Right click the hard disk you want to scan and click Properties.
- Click the Tools tab.
- Click Check Now.
- Select the Scan for and attempt recovery of bad sectors check box and click Start.
- Repeat steps 1-5 for all drives you want to check.
4. Disable The Search Index Service
Indexing
Services is a little application that uses a lot of CPU. By indexing
and updating lists of all the files on the computer, it helps you to do a
search for something faster as it scans the index list. But if you know
where your files are, you can disable this system service. It won’t do
any harm to you machine, whether you search often or not very often.
To disable the search index:
Click the
Start button, click
Control Panel, and type
index in the top-right search box. Click
Change how Windows searches.
Click
Modify.
Remove all locations by unchecking them and click
OK.
5. Cut Down on Background Applications
Many background
applications don’t need to run and only increase CPU cycles and, in
turn, the demand on your battery. Here’s a couple of things you can do
to cut down on background applications:
5a. Disable Windows Sidebar Gadgets
If
you don’t use the sidebar, you probably have it disabled already (right
click the Windows Sidebar icon in the system tray and click
Exit.)
If you use the Windows Sidebar, do you really need all your gadgets running? To disable Windows Sidebar gadgets:
Click the
Start button and click
Control Panel. Type
gadget in the top-right search box, and click
View list of running gadgets.
Next to the running gadgets, click
Remove.
5b. Diable Startup applications
To disable unneccessary startup applications,
follow this guide.
6. Optimize Visual Effects
Visual effects also use CPU and memory, which reduces system performance. To optimize visual effects:
Click the
Start button, click
Control Panel, and type
visual in the top-right search box. Click
Adjust the appearance and performance of Windows.
Select
Adjust for best performance and click
OK.
7. Turn off Windows Aero
Windows Aero enables the glass
effect you see on your Windows. This (surprise surprise) also uses CPU
and memory and should be disabled to increase performance. To disable
Windows Aero:
Right click the desktop and click
Personalization. Click
Window Color.
Uncheck
Enable transparency and click
OK.
8. Disable Your Wireless Internet & Bluetooth
If you’re
not using the internet or Bluetooth, consider disabling the hardware to
save resources. To disable your wireless, bluetooth, or both cards,
either:
A. Locate the switch on the side of your laptop (many laptops now have this) and turn your cards off.
or
B. Click the network icon in the system tray and click
Open Network and Sharing Center.
In the left-hand menu, click
Change adapter settings.
Right click your wireless connection and click
Disable.
Repeat for your Bluetooth device.
9. Keep Your Computer Cool
The
hotter your computer gets, the harder your fans have to work to keep it
cool and the slower your hardware performs. If using your laptop,
ensure there is proper ventilation by putting your laptop on a hard
surface (not buried in a pillow!) Also check your desktop has proper
ventilation by doing the following:
- Removing bunches of wires from the back of the PC.
- If your desktop has holes in its case for ventilation, ensure these holes are unrestricted.
- If your desktop is in a cabinet, leave the door open or install an intake and outtake fan to keep the cabinet cool.
- Consider adding more fans to your desktop.
- Keep your hardware clean.
Note:
Never use your laptop on a blanket or soft surface where airflow is
restricted. This will also keep your laptop working longer as hardware
is less likely to overheat and fail.
10. Uninstall Unneccessary Programs
If
you’re not using software and have no plans to use it in the future,
you can uninstall it to free up hard disk space and resources. Use the
following guides to help you remove unwanted software:
- Remove Bloatware with the PC Decrapifier
- Revo Uninstaller completely removes programs
11. Check for Bad Memory Sectors
Failing memory can be a cause for a slow PC. To check your memory for errors, follow this guide: Test Your Computer’s RAM.
