Cleanup and Optimization

In order to keep your computer running smoothly, it’s important to do regular maintenance and clean up your computer. This includes getting rid of unwanted files, running scans for errors, and optimizing settings. Doing this can help make your slow computer run faster, and can also help prevent it from becoming even slower in the future.

Let’s explore the different steps you can take to optimize and speed up your computer:

Clean up your disk space

Cleaning up your disk space is an important step to improve the performance of your computer. Over time, your hard drive can become cluttered with temporary files, application caches and archives, and logs. These files take up valuable disk space and can slow down your system as it’s trying to access them.

To clean up your disk space:

  1. Empty the Recycle Bin. When you delete a file on your computer, it goes into the Recycle Bin until you empty it. This takes up valuable disk space—so be sure to empty it regularly.
  2. Uninstall any applications or programs you no longer use on a regular basis by going to Control Panel > Uninstall a program and selecting which program you want to uninstall.
  3. Delete any duplicate files that have accumulated over time taking up unnecessary hard drive space (you may want to use an app like GoodSync or CCleaner for this).
  4. Compress large files that are hogging too much disk space (you may need an app like WinZip or 7-Zip for this).
  5. If you have kids that play PC games, delete those old saved games they don’t play anymore off their hard drive; some of those can be quite large!
  6. Delete cookies from websites (these will rebuild when you visit again so there is no need to keep them around): In Internet Explorer go Tools > Options > General tab > Browsing History > Settings and delete Cookies if something looks suspicious here.
  7. As well as cookies, delete temporary Internet files by opening IE> Tools – click Delete Navigation History > Temporary Internet Files.
  8. Clean out other setup history from Origin or Uplay installers — these are generally smaller but sometimes bigger than expected depending on what was installed originally so check there for folder size in relation to Temp Internet Files folder mentioned above.
  9. Make sure Windows Update is enabled so all security patches are kept current (this can drastically improve performance if its disabled) go Start – type in “Windows Update” – Check for updates.
  10. Defragment your hard drive which will reorganize how data stored and make seeking data more efficient go Start – Right-click Computer select Manage then click Defragment Now.

Uninstall unused programs

Removing programs you no longer need not only frees up space in your hard drive, but it also improves the speed of your computer. Unused or unnecessary programs can cause frequent crashing, making startup and daily use of your PC slow and problematic.

To uninstall an unwanted program, you first need to open the Programs and Features window by pressing the Windows key plus X and selecting “Programs and Features” from the list that appears. From here, you can scroll through the list of installed software on your device and click on any item that isn’t needed anymore to uninstall it. Additionally, combining similar tasks into one program will help keep your machine running optimally.

It is important to check regularly for updates for both hardware drivers and applications for better performance. Updates are critical if hardware drivers are out of date since then they cannot take advantage of new features when available. Application updates often have bug fixes which can make them run more efficiently. Undoubtedly, this will improve the overall performance of your machine in day-to-day operations. Keep all installed software up to date by regularly visiting manufacturer websites or searching online for available releases in order to ensure that your PC is running at an optimal level.

Disable startup programs

Even if you don’t suffer from regular computer slowdown, having a lot of applications and processes running in the background can affect overall system performance. Disabling unnecessary startup programs is an effective way to improve system performance and free up valuable resources for faster boottimes.

There are several different methods for disabling startup programs, depending on your operating system and other preferences. Start with Windows Task Manager or Mac OS X Activity Monitor which allow you to manage programs that are automatically launched when the computer starts up. It’s usually easy to determine which applications should be disabled by looking at their names, descriptions, or source locations. Additionally, you can use third-party tools such as CCleaner to further optimize your startup items so that only the essential programs run when your computer boots up.

Keep in mind that some of these applications are necessary for proper computer operation – make sure that you only disable those items which are completely unneeded or manually add new services if required for your workflow. With a bit of tweaking and research, it’s possible to greatly improve your system boot times with minimal effort!

Update your operating system

Having the most up to date operating system on your computer is essential for maintaining optimal performance and security. Updating your operating system can be an involved process, but it is well worth the effort. By running the latest version of either Windows or macOS, you will be able to guard against many common problems and ensure that your computer continues to run smoothly.

Before starting an update, make sure you back up any important files so they are not lost in the event of a problem. Additionally, you should ensure that all other programs on your computer are also updated so they do not conflict with each other or cause issues after the OS update has been completed. Once you have undertaken these precautions, you can then begin the update process through System Preferences (on macOS) or Settings (on Windows).

The update process may take several hours depending on how outdated the current version is and requires that the computer remain powered throughout this time. After it has finished updating, it may require restarting in order for all changes to take effect – bear this in mind if leaving your computer unattended overnight. After restarting and making sure all components are working as expected, then you can begin cleaning up any unnecessary files that may have collected during normal usage which could be slowing down performance of your device. This includes non-essential programs that can be removed to free up memory and resources as well as browser extensions or toolbars which use valuable bandwidth without providing any useful functionality.

Defragment your hard drive

It is important to periodically defragment your hard drive in order to optimize your computer’s performance. Fragmentation occurs when data and information on your hard drive is stored in multiple small pieces, as opposed to one large, continuous piece. This can slow down access time, as your computer needs to search multiple locations in order to find the data it is looking for.

Defragmentation works by re-organizing the existing data clusters into one contiguous block on the hard drive. By optimizing this storage layout, the computer will be able to locate data more efficiently and run more smoothly.

Different versions of Windows have different defragmentation options, so you may need to consult a manual or online tutorial in order to learn how to use your particular software’s built-in utilities. Alternatively, you can download a third-party program such as Auslogics Disk Defrag Pro for extra features and customization options not available through Windows alone.

Hardware Upgrades

One of the most common ways to speed up a slow computer is with hardware upgrades. Replacing or upgrading your computer’s RAM and storage, or even the processor can make a significant difference in performance. Depending on the age of your computer, there may be options for upgrades that you can take advantage of.

In this section, we’ll go over some of the hardware upgrades you can consider to give your computer a performance boost:

Upgrade your RAM

Adding more RAM (random access memory) to your computer is one of the most cost-effective ways to increase performance and speed up your slow PC. RAM is the temporary working memory for your computer, storing information about open applications and documents. You can think of it as a digital workbench that handles what’s active on your computer at any given time.

The more RAM you have, the more applications, programs and documents you can open concurrently. Most casual users will benefit from having 8GB or more of RAM installed in their PCs. If you plan to use intensive programs like video editing or video gaming, 16GB or more may be suitable.

Upgrading additional RAM is relatively simple; check with your PC provider’s manual or online support site to determine standards and types available for installation in your hardware configuration. The direct upgrade path involves:

  • Taking off the sides of your PC.
  • Locating an available memory slot – usually an SODIMM – installing the new module at by clipping into place.
  • Replacing outer case panels once done.

Alternatively, if you don’t feel comfortable opening up a PC unit yourself, local repair organizations often provide technical assistance for upgrades such as this one.

Upgrade your hard drive

Upgrading your hard drive is one of the most common hardware related tasks for improving system performance. If you’ve been using the same PC for a while, chances are your current hard drive will benefit from a fresh installation of Windows and some basic software updates. Otherwise, you may need to look into adding extra storage by upgrading it to a larger capacity.

When selecting an upgrade hard drive, consider purchasing one with a higher RPM rating and more cache memory to give your system an extra boost in speeding up file access while multi-tasking. SDD drives also provide extra storage space that helps store more data at faster speeds than traditional spinning disks; however these are typically more expensive and can be difficult to install if you don’t have the necessary tools or experience in replacing components on computers.

If you decide to bite the bullet and purchase a new hard drive, make sure to do plenty of research as some components may not be compatible with certain systems—for example, there are differences between 2.5 inch and 3.5 inch drives—so always double check whether or not your chosen unit will fit into your current PC setup before buying anything!

Upgrade your processor

An old, slow processor can be one of the main causes behind a slow PC. Upgrading your processor is a relatively inexpensive way to potentially boost your computer’s performance and it can usually be done easily, with minimal fuss.

When choosing a new processor for an upgrade or replacement, it’s important to choose one that is compatible with your existing motherboard. Motherboards have different sockets and each socket is designed for specific types of processors – so you’ll need to check what type of socket your current motherboard has before you buy a new CPU (Central Processing Unit).

Also, make sure you get the correct clock speed and number of cores for the job you are trying to do – higher clock speeds often equal better performance and more cores means simultaneous multitasking capabilities.

Whatever new processor you decide on, it’s always wise to invest in quality cooling solutions such as liquid cooling or thermal paste to ensure that your new hardware won’t become damaged due to overheating.

Upgrade your graphics card

Your graphics card is responsible for how quickly and accurately your display renders visuals when playing video games or editing videos. If you’re a serious PC gamer or video editor, it’s worth investing in a quality graphics card. Upgrading your graphics card is often the single best way to improve performance, and you can usually swap out the old card with your new one without making any other changes.

Before purchasing a new graphics card, determine which type of expansion slot is available on your motherboard (PCIe, AGP) so you can purchase an appropriate model. Additionally, take into account the power of your system by checking the wattage rating listed on your current PSU (power supply unit). When selecting a model based on these factors, look at hardware specifications such as CUDA cores (dedicated processors on an NVIDIA GPU), RAM bus width/bandwidth (how quickly data can be moved from/to RAM), texture fill rate (how fast textures are applied to 3D models), clock speeds, number of output ports and heat dissipation capabilities (heat sink size).

It’s also important to be aware that some manufacturers create cards “overclocked” – which means that they are designed to perform above standard speeds. If you’re looking for a more powerful option but don’t want to sacrifice compatibility with other hardware components in your computer system, this could be a viable route to take. Finally, make sure you install any necessary software drivers that come with the graphics card before use – overclocked cards often require extra configuration steps during installation in order for them to work properly.

Software Upgrades

Updating your system’s software can be a great way to speed up your computer. Make sure all of your software is up-to-date with the most recent versions. This will eliminate any potential compatibility issues and help address any security vulnerabilities that could be causing your computer to slow down. Additionally, some software updates may include bug fixes that can help improve your computer’s performance.

Update your drivers

Outdated drivers can significantly impact the performance of your computer system. To keep up with the latest technology and stay safe online, it is important to update your drivers regularly. It is recommended that you upgrade device drivers at least once every few months or whenever a new version of the driver becomes available in order to get the best performance out of your computer hardware.

It is important to note that not all drivers require an upgrade. It is also important to read any release notes carefully in case there are compatibility issues with specific devices or operating systems. New releases may cause other hardware problems or application incompatibilities, so it is best to have a backup plan in place before performing any upgrades.

Upgrading your device drivers can be done manually or via an automated tool such as Driver Update software. Manual upgrades require downloading the individual driver from each manufacturer website and installing them one by one, which can be time consuming and tedious for users unfamiliar with computers and hardware components. Automated tools often make upgrading easier, faster and more reliable as they be used to detect outdated and missing drivers on both Windows PC’s and Macs making sure that no component is left behind during installation.

Install anti-malware software

In order to maximize the security of your system and keep it running smoothly, installing anti-malware software is essential. Anti-malware software products continuously monitor your system, shielding it from malicious software that can compromise data or cause system slowdowns and crashes. They detect and remove viruses, spyware, and other malicious software before they can do any harm. Additionally, they scan downloaded files for viruses and provide real-time protection against potential threats via continuous monitoring of activity on your PC.

Before installing any anti-malware software, be sure to get a recommendation from a trusted source such as an IT professional or trusted online review site. Be sure to read through the features included with each product so you know what you are getting for your money. Once you have selected an anti-malware program that meets your need and budget, follow the provided installation instructions carefully – some products require users to agree to a license agreement before installation will begin. Once installed, anti-malware programs typically require a one time activation process in order for them to start protecting your computer correctly.

Install a VPN

A Virtual Private Network (VPN) is a secure connection between your computer and the internet. It routes your web traffic through an encrypted tunnel, which makes it difficult for hackers to access your data or monitor your activity. With a VPN, all of your communication is encrypted and secure.

This can help improve the performance of slow computers, as it can help block malicious websites and limit the amount of unwanted advertisements, pop-ups, and tracking software that may slow down a computer’s speed. Additionally, VPNs also help protect against cybercriminals who might seek to gain access to sensitive data or steal personal information.

Installing a reliable VPN is one of the most effective ways to ensure your computer’s security while also helping improve its performance.

Install a disk cleaner

In order to keep your computer running smoothly, you should install a disk cleaner program on it. Disk cleaners are designed to scan through the hard drive and identify areas of the system that may be slowing it down, as well as any corrupt or unnecessary files. Once identified, these issues can then be addressed, such as removing unnecessary files or programs that are responsible for slowing down the system’s performance.

Another way to ensure an efficient and fast-running PC is by using a defragmenter program. Over time, the hard drive of a computer will become fragmented due to its writing process – meaning data is scattered all over the hard drive instead of being stored in one particular area. Defragmenter programs help reorganize this data into neat folders, increasing storage space and overall performance.

By performing regular updates on software installed on your computer can also speed up your system’s performance. Updates contain fixes for known bugs that can affect the stability and performance of your computer; therefore it is always important to make sure to regularly update software packages like Microsoft Office and Adobe Acrobat Reader for example. Some operating systems offer automated update services so you never have to worry about missing an important patch or upgrade!


Taking proper care of your computer can help it run faster and more efficiently. This does not involve intense, laborious repairs but rather simple steps that can help you maintain your computer and keep it running smoothly. In this blog, we will cover 10 computer repair tips to help speed up your slow PC:

Clean up your registry

Cleaning up your registry can be an effective way to speed up your computer. Your registry is a database that stores essential information to help Windows run more efficiently and quickly. Over time, the registry can become congested with obsolete and invalid data entries due to installation, un-installation, and general use of your computer over time. Cleaning your registry can help reduce system errors and re-establish stability on your PC.

Before you attempt this repair project on your own be aware that any mistake when editing the registry has the potential to cause serious issues with the functionality of Windows. It is best practice to back up the entire registry before getting started – if you don’t have a professional-grade backup program installed on your computer, you should strongly consider installing one before starting this task.

Once you’ve created a reliable backup of your registry, there are two main ways you can go about cleaning it–by manually removing entries yourself or using dedicated software. As a beginner user, we suggest using software as it automates most aspects of administering the task and minimizes risks associated with editing sensitive areas of the system environment. Typically, these programs provide detailed reports outlining items that need attention so users are able to make informed decisions about how they want their registries handled without damaging important files or settings in Windows.

Clean up your browser

In order to keep your computer running at optimal speed, regular browser maintenance is essential. Over time, your web browsers can accumulate temporary files, error messages and other clutter that works against you when you’re trying to navigate the internet.

It’s important to look through all of your web browsers, including Chrome, Firefox, Safari and Microsoft Edge (or Internet Explorer), and delete any temporary files. Additionally, you should check that you don’t have too many tabs open as this can slow down the browser’s performance.

To ensure optimal browsing speeds, you should also configure your browser settings like disabling certain plugins which can be a resource hog in some cases. Finally, it’s always a good idea to keep your browsers updated with the latest versions as updates often include bug fixes and compatibility upgrades which help keep them running quickly and smoothly.

Check for system errors

When it comes to maintaining any computer system, it is important to check for errors. Errors can range from simple problems such as frustrating lag time when completing tasks, to serious ones such as a complete system crash or loss of valuable data.

System errors can be caused by anything from hardware malfunctions, outdated drivers or programs, viruses, and more.

To ensure your system’s reliability and efficiency, regular checks should be done for system errors. Common ways of doing this include:

  • Running diagnostic tests on your hardware components.
  • Restarting the computer occasionally to clear out unnecessary temporary files and programs that may be running in the background.
  • Uninstalling any unnecessary software that may be causing conflicts with existing programs or slowing down performance.
  • Checking for new operating system updates that may improve stability or performance.
  • To help protect against viruses and malicious attacks it is also recommended to regularly run virus scans and install a firewall if necessary.

System errors should always be taken seriously as they can lead to data loss and further damage of your computer if not addressed promptly. If you are unsure how to properly maintain and troubleshoot your system yourself it is recommended to enlist the services of an experienced IT technician who can diagnose issues quickly and accurately without compromising the safety of your data.

Check for virus and malware

It’s essential to check your computer for viruses and malware on a regular basis. Doing so not only prevents malicious software from stealing your data or corrupting your system, but it also ensures that you’re using the latest security measures and avoiding online threats. Here are some tips for keeping your computer safe and virus-free:

  • Install antivirus software: For Windows PCs, install a comprehensive antivirus program from a trusted source. Make sure to keep it up to date with the latest security updates. For Macs, use Apple’s built-in malware protection – it will detect and delete known viruses, Trojan horses, worms, and other malicious programs before they can do damage.
  • Scan for virus regularly: To check for viruses often, schedule regular scans with your antivirus software or use free online scan services such as Bitdefender’s Virus Scanner. Be sure to store any scanned files away from potential infection points (like external drives).
  • Keep operating system up-to-date: Make sure that your operating system is always running the most recent version of software updates; this ensures that you remain protected against the latest threats. Also be sure to regularly uninstall programs you no longer use – this will help free up processing power and reduce potential vulnerabilities in the future.
  • Use password protection: Use secure passwords or passphrases across all accounts at least eight characters long – mixing upper/lowercase letters, numbers, and symbols creates an even stronger password defense than simpler phrases do. Also make sure to never reuse passwords; each account should have its own unique login credentials.

By implementing strong virus defenses and regularly scanning for malware, you can ensure that your computer remains clean and secure in the face of today’s internet threats.


Troubleshooting is an important step when it comes to computer repair. It is important to understand what the underlying problem might be before attempting to fix it. This can save you time and money by ruling out possible issues before attempting repairs.

In this section, we will be discussing some of the most common troubleshooting tips to help you diagnose and repair a slow computer efficiently:

Check for hardware issues

One of the most common reasons for slow computer performance is hardware failure. Hardware problems can be difficult to diagnose and repair, as they often require professional help. To investigate a hardware issue, run a diagnostic test on your system. Your computer’s operating system has built-in diagnostic tools that you can use to determine where the issue is coming from.

Hardware failures can cause a variety of issues, such as slow loading speeds or complete system crashes. If your computer cannot boot properly or you cannot get into the operating system, you may need to take it to an expert for further investigation and repair. In some cases, the only way to find out why a system is not working correctly is by opening up the case and inspecting components such as memory modules, power supply, disk drive interface and cooling fans.

If you suspect your computer’s hard drive has failed, make sure to back up any important data before attempting any repairs. By taking regular backups with an external storage device, you can avoid data loss if anything happens to your PC’s internal storage media.

Check for software issues

When troubleshooting computer problems, one of the first steps is to check for software issues that may be causing your computer to run slowly or having problems with application or programs. Once you have determined hardware is not the cause, there are several software-related issues that may need to be addressed in order to get your computer running faster.

Begin by making sure your computer is up-to-date with the most recent patches and updates from Microsoft. This can help to eliminate any cybersecurity threats that may be affecting the system, as well as any performance bottlenecks caused by outdated programs or drivers. The anti-virus program should also be checked and updated regularly if it is not running on a continual basis.

Plugins and extensions can also hinder performance, especially if they are not being used very often. Removing unnecessary add-ons from web browsers such as Chrome or Firefox can help make these applications run faster when they are opened up on the desktop. For applications such as Adobe Photoshop, consider disabling unnecessary options and features which will reduce memory usage from your system’s RAM and make starting the program much quicker.

Finally, look at auto-start programs in Windows which may launch themselves when you turn on your machine; this will also affect overall performance. Disabling startup processes where possible can free up valuable resources for other tasks and speed up boot times significantly.

Check for network issues

In order to get the best performance out of your computer, it is important to check both the hardwired and wireless connections when troubleshooting. Start by disconnecting any external devices and then rebooting your computer.

If that doesn’t fix the problem, the network connection may be the culprit. Check for possible conflicts with any other wireless devices in your vicinity or too many connected devices on your existing network.

Next, you should check your router settings to ensure you are taking advantage of the most up-to-date features such as Quality of Service (QoS)port forwarding, and VPNs (Virtual Private Networks). Change any outdated settings that could be slowing down your connection. Finally, verify that you have updated drivers for both wired and wireless hardware as this will help maximize bandwidth efficiency. Clear any type of temporary Internet files, cookies, and other items which can clog up system memory causing issues with downloads or streaming videos online.

Check for power issues

Periodically checking the power cords on your components is important to ensure that your PC is not operating on a weakened voltage or inconsistent power supply. Inspect the plugs and sockets connected to your system and make sure they are firmly in place. Check the cable lengths and investigate any frayed connections, loosened screws, or rust issues.

If you have an additional plug present which could be used to power additional components, make sure that it is unplugged or its circuit breaker is switched off. Using an incorrect outlet can cause one of your devices to malfunction. If you suspect any faulty connections, contact a qualified technician for help resolving the issue before taking further steps.
