It help to perform maintenance or correct problems with a computer system.

System maintenance is an umbrella term that encompasses various forms of computer maintenance needed to keep a system running. The two main components of system maintenance are preventive and corrective maintenance. Preventive maintenance involves taking measures to help keep the system functioning, whereas corrective maintenance involves the replacement or repair of a system or its components after they have already failed.

Preventive Maintenance

Preventive maintenance is defined as the proactive maintenance of equipment before a fault or failure occurs. Preventive maintenance involves routine tasks to ensure that your system is running optimally and to avoid problems before they arise. This is similar to routine maintenance performed on a car: In the same way you need to periodically check the oil, lights, engine, and other parts of the car in order for it to run smoothly, the same principle applies to preventive maintenance for a computer. There are several preventative measures you can take, including installing Windows updates, scanning for viruses and malware, and running cleaning programs. Anti-virus and anti-malware scans should be run at least once a week. Be sure to run updates for these programs whenever they"re released, as new viruses and malware spring up constantly. Keeping your network secure, installing a firewall, and using safe downloading practices can protect your computer and any information on it from being compromised. Power surges and overheating can destroy electronic equipment, so protect your hardware by investing in a surge protector and cleaning your equipment periodically to remove dust. Should any preventative measures fail, it is always a good idea to have a backup for important files: Invest in an external hard drive to save any important files should your computer need replacing.

Corrective Maintenance

Corrective maintenance, commonly referred to as 'repair,' is the correction of a problem after the computer has already broken down. The goal of this form of maintenance is to restore operability to the system by either correcting the problem or replacing the damaged components. Common corrective measures involve removing viruses and malware, uninstalling harmful programs, reformatting, and running a system restore, among others. Many common computer problems are easily fixed and don't require an IT professional. To perform corrective maintenance, it is important to first diagnose the problem and figure out the root cause. If you are unsure of the cause or how to fix your problem, consulting an IT professional would be the best course of action.

Making Your Machine More Reliable

There are many small steps one can take to optimize computer performance so it is faster and more reliable. Not having sufficient hard-drive space can slow down your computer significantly. Clear out hard-drive space by removing unnecessary programs and defragmenting your hard drive. Defragmentation helps speed up your computer and should be performed at least once a month. When you install new programs, you will often be presented with the option of having the program start automatically when you turn on the computer; sometimes, this is the default option. The more programs you have running automatically, the slower the performance of your computer, so you should disable this whenever possible. To make your Internet connection run faster, one of the simplest things you can do is to clear your Web history and delete temporary Internet files. The more often you perform these actions, the less time it takes, so try to aim for at least once a week. Spyware and malware can also be the cause of slow Internet speed. Make sure you have anti-malware programs installed, update them whenever necessary, and run a scan at least once a week. You can avoid spyware and malware by exercising safe downloading practices, such as downloading from reputable sites. If you are unsure of the safety or legitimacy of a program, run a Google search to see what information you can find, and it you're still in doubt, refrain from installing the program completely.

Today’s computers come in many different shapes and sizes, and each keeps us connected to our digital world at any given time. Whether you depend on your collection of devices for work or play, keeping them in impeccable, unblemished condition is of the utmost importance. From their cosmetic appeal to their operational functionality, a well-maintained computer looks good, lasts longer, and performs reliably.

Keeping your PC in tip-top condition lengthens the life of your PC, both internally and externally. A glitchy operating system, overheating CPU, or fast-draining battery are avoidable computer woes that a bit of regular maintenance could defend against. Let’s take a look at these 10 essential maintenance tips, so your PC will see many more years of powerful performance and sleek appeal.

1. Protect with padding

Everyone has been there; drops, bumps, and slips result in unsightly cosmetic dings that leave your computer looking less-than-loved. If you’re like most people who travel with their PC, safeguarding against accidents can feel next to impossible when packing your PC away into a carry-on. An exposed laptop is vulnerable to all of the elements of travel you likely want to protect it from.

Whether you’re traveling business-class or to a classroom across campus, shielding your PC against the elements starts with a protective case. There are a few different styles of protection that offer differing levels of armor and functionality. These include:

Skins

Functioning as a full-body laptop sticker, laptop skins are best for protecting the chassis from light damage and scratches.

Hardshell snap-on covers

Polycarbonate, plastic, or rubberized hard shell laptop covers protect your PC while still granting easy access to ports, buttons, lights, and fans.

Sleeves

A simple, soft, envelope-style pouch typically made of gentle materials like nylon, polyester, suede, or microfiber, laptop sleeves are lightweight protection.

Messenger bag

A shoulder bag specifically designed to accommodate your laptop and necessary peripherals, the dedicated laptop messenger bag offers the most padded protection.

2. Organize cords

The only thing more frustrating than dealing with long, confusing cables is getting them all mixed up and tangled in the process. Keeping your digital world connected is a must, so nixing the cables isn’t a feasible option. Taking the time to declutter and organize the snake-like mass of wires spawning from your power strip and PC ports is a great first step for both desktop and laptop users. Try these wire organization tips:

A rotating power strip

Traditional power strips offer a single line or panel of surge inputs. A rotating power strip gives you the freedom to modify the positioning of your many chargers, monitors, and docks.

Color-coding cables

Computer cables tend to be two colors; black and white. Organizing your mess of wires may be as simple as color coding them with reds, blues, yellows, greens, and or using labels in distinguishable hues.

Cable clips

Wire management is made simple when you attach cable clips to your desk, wall, or floor. These small clips are designed to hold cables of all different sizes.

Organizer panel

Functioning as a panel of cable clips, a wire organizer panel accommodates multiple wires. Stick it in place with an adhesive or keep it desk-side when you use a weighted panel.

Pro tip: Be sure to keep your wires away from any footpaths. Tripping over wires could result in the toppling of your devices, doing more damage in an instant than years of use could ever do.

3. Update your operating system

If you’re looking for basic computer maintenance, keeping your operating system up to date is one of the easiest solutions. Regardless of whether you’re a Windows, Mac, or Linux loyalist, updating your PC when new patches are available ensures your PC stays at the cutting-edge of performance power.

Windows 10 is known for keeping users in-tune with once-a-day update checks. This automated scan occurs in the background and always notifies you if there are any important software or operating system patches that need to be made. The end goal is to optimize your PC performance, so when Windows suggests you update, you should do it.

Pro-tip: Some updates take longer than others. Set aside time before bedtime or during a daytime break to let Windows do its thing without interrupting your workflow.

4. Unplug to avoid overcharging

With heightened dependence on wireless devices, optimizing battery power is a top priority for many. There are few things more dreadful than a draining battery when you’ve got hours of work and play left on your day’s schedule. However, it’s better to resist the temptation of plugging in the moment your PC falls under 50% battery life.

Unnecessary charging can lead to overcharging, which then leads to regenerative capability deterioration. This often looks like a laptop that can’t hold a charge as well as it could in its earlier days.

Being shackled to the weight of a charger defeats the purpose of a laptop’s wireless portability. To avoid a bad battery fate, unplug your device after it reaches 100% charge, and don’t plug in until power is actually low.

5. Purge your system of junk files and programs

Computers tend to show their age best in the number of unused files living on their hard drives. Useless programs and old junk files likely take up more space than you realize. From old versions of software to retired versions of your resume, your PC is sure to have its fair share of digital debris festering on your desktop or in your start menu. These programs and files can quickly turn into performance hogs if they continue to accumulate.

Before your computer gets to a point where it’s begging for more storage space, use these PC purge tips to relieve your system.

• Uninstall trialware
• Run disk cleanup software
• Empty the recycle bin
• Delete temporary files
• Remove cache of offline web pages

6. Run regular antivirus scans

Malware attacks can sneak up on you at any given moment, and in the event one does, having a savvy antivirus living on your PC will protect you against the damage viruses bring. Weekly antivirus scans ensure your computer is always clear of malicious software infections. A basic scan will examine your computer for any glaring dangers or outstanding activity.

For those who are frequent web-users and download programs and files regularly, consider running a virus scan twice a week. It’s always better to err on the side of safety, especially when your personal data could be at risk.

Malware infections can compromise the performance of your computer and expose your confidential information to third-party cybercriminals. Depending on the type of malware installed on your system, a virus could also:

• Slow web browser speeds
• Disrupt network connections
• Freeze or crash your system
• Alter computer settings
• Allow unauthorized access to system resources

By running regular antivirus scans you can rest assured that nothing slips by. Be sure to choose an antivirus scan servicer that also scans all of your downloads, too.

7. Clean the keyboard and case

You’d be surprised to see just how much dust and debris lives underneath your keyboard’s keys. From food crumbs and dog hairs to dust and dirt, and everything else that can fit in between the keys, a number of dirty particles can clog your keyboard. This usually results in sticky or difficult-to-press buttons.

Clearing out these hard-to-reach parts of your laptop or desktop setup is most easily done with a compressed air canister, available from office supply stores, computer stores, and hardware stores.

For external keyboards

Unplug the keyboard from the USB port or power it off if it’s wireless. Tilt the keyboard upside down and shake any loose debris out first. Spray compressed air at an angle and approximately 1-inch away from the keys. Use a damp microfiber cloth to finish the job, removing any excess dust or grime.

For the laptop user

Power your laptop off and unplug any USB or power supply inputs. Tilt the laptop upside down and gently tap it to encourage any loose debris to come out. Set the laptop down in its natural position and spray between keys from about 1-inch away. Spray in short bursts moving from one side of the keyboard to the other.

If you find certain spots tougher to clean than others, use a cotton ball dipped in isopropyl alcohol as a great alternative. Alcohol evaporates more quickly than water which makes it the perfect solution for hardened debris.

Pro-tip: When cleaning your laptop or desktop, absolutely avoid pouring any type of liquid onto the body. Water and electronic devices do not mix well and could result in extreme damage to your computer.

8. Update your passwords

Believe it or not, updating your passwords is a task as crucial as backing up your data. Verizon’s 2017 Data Breach Investigations Report found that an alarming 81% of hacking-related breaches leveraged either stolen and/or weak passwords [1]. Poor password behavior encompasses everything from using the same password for every account to using simple, guessable passwords like “password” or “123456.”

When it comes to basic computer maintenance, protecting your digital world against cybercriminals should always be at the forefront of your task list. No security system is perfect, and more today than ever before, consumers are realizing this on a large scale.

If you’re overdue for a password update, consider using these strong password generation tips:

1. Use at least 10 characters
2. Use a combination of uppercase and lowercase letters
3. Include both numbers and special symbols
4. Add emoticons if possible (:O, :(, :D, :), T.T)

A strong password safeguards all of your data against potential third-party hackers which is precisely why it’s such an essential part of computer maintenance.

9. Organize your data

It’s easy to let your computer’s data organization run awry when your work and play lifestyle doesn’t leave much time for calculated file management. Whether it’s old music files from your garage band days or downloaded add-ons for your favorite simulation game, your PC’s many folders can grow crowded.

If you can’t remember the last time you took a look through your downloads folder, you’re likely overdue for a visit. The same applies to the rest of your default folders (documents, photos, etc.).

Dealing with a cluttered desktop or crowded computer folders may be a daunting task, but with these tips and tricks, you’ll be well on your way to a functioning system of files and folders.

Create large, main folders

Everyone uses their computers for different primary purposes. A freelance writer will likely have completely different main folder assignments than a professional gamer or a business owner. It’s important to narrow down your digital world into easy folder divisions to make your first round of organization a breeze, and your future rounds even easier.

Create small sub-folders

Within your larger primary folders, smaller sub-folders make your organization operation even smoother. Being able to categorize files by their functionality or content will help you access them whenever you need them. No search button necessary.

Empty your downloads folder

Your downloads folder should function as a temporary cache for recently downloaded files. Get into the habit of placing recent downloads in their proper folders or deleting them once they’ve served their purpose.

Clear your desktop

When you power on your computer and saddle up for your day’s work or some light social media browsing, you want to be able to do so without the stress of clutter. Clear your desktop of any files, folders, or programs you don’t need readily available at every power-on.

Choose thoughtful filenames

If you’re frequently saving images, PDFs, and other common files, you know how easy it is to type in gibberish for a successful “Save As” operation. Instead of rushing through, take the time to come up with intentional file names so you always know what’s living on your hard drive and where it’s located.

10. Back up your data

Part of owning a modern computer is to prepare for the unexpected. Sudden crashes, untimely glitches, and random hardware failure all have the potential to damage the data living on your PC. Backing up files is one of the most vital computer maintenance procedures PC users can do for themselves. That’s why we’ve ranked it at our final spot. Your computer is replaceable, but without a backup, your information is not.

Full backups are usually done on storage-heavy external hard drives and on the cloud. By making duplicate copies of everything on your PC (actually having your data in 3 places is safest), all of your valuable data lives both on your computer and inside of the external drive or cloud.
