The good folks over at iolo have come up with some great ideas on how to clean up your PC to improve performance and to also speed up your hard drive. It is a good idea to keep your PC clean and free of dust so it won't be bogged down and it begins to affect performance.
I would have to agree with iolo with this list of ways to clean your PC. It is an often overlooked aspect of owning a desktop or even a laptop. Dust and improper cleaning will be the silent killer of your computer. So without further hesitation here are some great tips on cleaning your PC.
How NOT to Clean Your Hardware
Be sure to unplug your computer before you start. Second, never spray liquid cleaners directly into your system. If you use any liquid to get rid of dust, pour it lightly onto a cloth first.
Fans and Vents
When it comes to the hardware portion of a routine PC cleanup, your best friend is a can of compressed air, which will allow you to blast every fan and vent on the outside of the tower.
Tackling the Interior
First, touch something metal for several seconds to ground yourself and prevent static electricity from damaging the sensitive inside components of your system. Next, remove any added video or audio cards and place them aside. Other components, like audio connectors and port extensions, can be taken out too. Be careful when using a vacuum—it's effective for much of the built-up dust, but don't get it near any PC components. Get out the brush and compressed air you used for the exterior and very gently get to work on the motherboard and slots.
Piecing It Back Together
Before you seal the machine back up, carefully clean all of the components you set aside with your brush. Then put them back where they belong, ensuring that you replaced everything to its rightful position and you didn't leave any cleaning materials inside the case. Close it all up, but wait at least half an hour before plugging in your now-clean PC and booting it up again.
Clearing Out the CRUDD
Go through your applications folders. Chances are, there will be some programs listed you've barely even noticed before—some of them may have come pre-installed and others may have installed themselves without your knowledge. Regardless, if you don’t need them, you can delete them.
Set aside some time to tackle updating all the software you've been putting off. Installing software updates will speed up your system and make sure your computer is protected against many of the latest security threats, which get patched regularly within programs but remain unpatched in older versions.
3. Hard Drive
Benefits of Backup
Back up your files onto an external hard drive or cloud storage service. Then go through your library and delete some of the stuff you don't use very often anymore.
Get Rid of Fragmented Data
Run a defragmenter to remove clutter from your hard drive. Like many of the processes on this list, you should do it more regularly than once a year.
