When you unpacked your PC the first time you got it home, or it was installed in your office, it worked like a dream. The system started quickly, programs opened quickly, did their job as expected and closed down with no problems.
Then after a few months, or maybe even weeks, the rot set in. Your PC started taking ages to start up, programs took an age to open and load your data, and then to add insult to injury, takes an eternity to close down.
So what’s going on? Why the big difference in performance? And more to the point, can you get it working as it used to again? The good news is basically “Yes, you can”, but there are so many things that contribute to the lack of performance that it’s difficult to know exactly what is causing the problem. In most cases, it can be a combination of different factors all working against each other to bring your system to its knees.
Here is a list of things to try to get back some or all of the performance you used to get with your PC.
1 Free up disk space
We’re all guilty of saving more files, documents and images than we really need. In some cases, we save something and then cannot remember where we put it, so we end up with a lot of “lost” files scattered around our hard disk.
Another common thing is to keep copies of files, or older versions “just in case”. There’s definitely nothing wrong with keeping backups – I recommend it. However, keep your backups on another disk – preferably a removable one such as a CD or DVD – or maybe even on a flash memory drive.
When the computer’s hard disk is getting full, the computer starts to have a hard time finding space to store things – including temporary files that it uses during its normal operation. So, we need to clean out all the rubbish. Delete unused files and folders (taking care not to delete system files and folders) to free up some of that wasted space.
Using browsers on the Internet leaves a huge number of temporary files on your hard disk. You can remove them by opening My Computer, right-clicking the C: drive and clicking the Disk Cleanup button.
2 Repair Disk Errors
From time to time, the computer’s filing system gets a bit confused and data is not saved properly. Files get cross-linked or truncated making them unreadable. They are still taking up disk space though, so you need to repair the disk to recover the documents.
Click the Start button, and select Run. In the prompt that opens, enter
Chkdsk c: /f
This will run the disk checking utility that sorts out cross-linked files etc.
It might say that you can’t run chkdsk but you can schedule it to run at the next bootup. Choose the option to run Chkdsk at startup and then reboot your PC. Chkdsk will automatically run, detect and repair any errors it finds.
3 Defragment your disk
Your disk doesn’t really get fragmented, but your files do. It means that the file is split up into small pieces, each stored in different places on your hard disk. When you want to load that file into a program, it has to go and gather up all the pieces and fix them all back together again. This takes a lot longer than if the file was already in one piece.
Fragmentation happens when you create files, add to them and re-save them or move them, delete them, install programs, load photos etc.
As disk space is used and released, the available spaces on the disk become small and scattered over different parts of the disk. As a result, if you have a large file, the filing system can’t find a large enough space to store it, so it has to split it into smaller pieces and save the fragments in the available spaces.
This takes more time to save the file, and more time to re-load it as all the pieces have to be gathered up and put back together.
Some people will tell you that with modern disks, this is not such a problem because they are so much faster. This is true to some extent, but in practice, it really does seem to make a difference. It is certainly true on slightly older PCs.
Luckily, we have a tool called a defragmenter.
1. Open My Computer.
2. Right-click the local disk volume that you want to defragment, and then click Properties.
3. On the Tools tab, click Defragment Now.
4. Click Defragment.
If your disk is severely fragmented, this might take a long time to complete. It’s best to leave the PC to get on with it than try and do something at the same time. Once done, try to remember to do it about once a month – it will take a lot less time if done regularly.
4 Remove Software You Don’t Use Any More
When you click Start and then All Programs, is the list you are presented with getting bigger and bigger? The chances are that there are programs in there that you haven’t used for months. Maybe you even forgot they were there.
These unused programs are occupying disk space (see Tip 1). But some programs can use more than disk space; they can use system memory and processor time as well. When you install the software for a printer, for example, it very often includes a program that runs in the background, monitoring the printer status etc. You might see evidence of this as an icon in the bottom-right corner of your screen, unless you hide the unused icons.
Open your control panel, select Add or Remove Programs and wait for the list of programs to appear. Then go down the list and remove anything that you no longer use.
5 Remove Spyware and Viruses
If you’re a regular Internet user, receive spam email or have installed unknown, free programs from a web site, you could have one or more viruses or spyware programs installed. Not only is this a security risk, it could damage files on your computer. In addition, the spyware is eating into your processor time which will slow your computer down.
Install and run spyware removers and antivirus software. There are a number of free ones available, such as AdAware and AVG.
6 Clean the Registry
The Registry is a set of system files where Windows and programs that you install save data and settings about themselves. Some programs are not very good at cleaning up after themselves when you uninstall them, so data gets left behind, and links get lost.
Windows itself is just as guilty of leaving the Registry in a mess and provides no tools to clean it up. However, Microsoft have created RegClean a free tool you can download from their website. It does a very basic job though, and doesn’t fix all problems.
Several 3rd-party Registry cleaners do exist, but you generally have to pay for them.
7 Delete Unused Network Connections
If you connect to a network, whether it’s in an office or at home, if you have set up a network connection, Windows will spend time trying to establish that connection when it starts up. If it can’t make the connection after a specified time, it gives up (called a time-out) and tries the next one. If computers to which you connect are frequently switched off, Windows will not make the connection, so you’ll have to wait until the connection attempt “times out”.
Delete network connections you don’t ever use so that you don’t waste time trying to connect.
8 Remove Fonts that you Never Use
Many people, when they first get a PC, discover fonts that they can download from the Internet, or see discs of 1000 fonts in their local PC store, and catch font-fever. In no time at all, they have a huge selection of fonts on their PC, most of which are never used.
Some software installs additional fonts without you even knowing it, too. Each of those fonts uses up a little disk space and some system memory. The more fonts you have, the more resources are used up and your system takes a hit in performance.
Go to your Control Panel, open up Fonts and delete the ones you never use.
9 Keep Drivers Up-To-Date
Drivers are small programs that let Windows access a certain piece of hardware, such as the video card, sound card, or a printer. New hardware often comes with drivers that were hurriedly put together, almost as an after-thought. In some cases, they rely on generic Windows drivers for them to work. These are seldom optimised for a particular piece of hardware.
After the product has gone on sale, the developers have more time to improve the drivers and eliminate errors in them. Very often, these updated drivers improve the speed of the device, or use fewer resources, so it is worthwhile checking with the manufacturer to see if they have updated drivers. You will often find them by going to the manufacturer’s website and looking for the Downloads or Support links.
10 Reinstall Windows
This is a very extreme way of getting your PC to work the way it did before, and I’d only recommend it if your PC is performing very badly, crashes often, or often runs a disk check when you start it up.
Whatever you do, backup your important data, photos, files etc., before you start.
Bear in mind that if you do a full, clean installation, you will also have to re-install any programs that you had installed before.
You will need your original Windows installation disk or rescue disk that came with your PC. If you don’t know what you’re doing, seek further advice, or leave your system as it is.
