How to Speed up Computer with Proven Ways?

Part 1: Common Causes of a Slow Computer

Before fixing the problem, it helps to understand what is slowing your machine down in the first place. Here are the most common culprits that prevent you from getting the better computer performance:

• Low disk space: When your storage drive is nearly full, Windows has no room to create temporary files, which significantly slows down operations.
• Malware and viruses: Malicious software runs silently in the background, draining system resources and degrading performance over time.
• Outdated Windows or drivers: Skipping system updates means missing critical performance patches and security fixes.
• Fragmented or aging hard drive (HDD): Mechanical drives slow down considerably as data becomes fragmented across the disk.
• Insufficient RAM: Running memory-heavy applications on a system with limited RAM causes constant disk swapping, which is much slower than actual memory.

Identifying which of these applies to your machine is the first step toward a noticeably faster computer.

2. How to Make PC Run Faster?

Here are several proven manual methods to improve PC performance. Work through each one and you will notice a meaningful difference in day-to-day responsiveness.

Method 1: Uninstall Unused Apps

Unused applications do not just waste disk space, many also run background processes, schedule automatic updates, and load services at startup. Removing them is one of the best ways to speed up computer performance with zero cost.

• Press Windows + I to open Settings. Go to Apps > Installed apps.

• Sort by Size or Install Date to identify bloatware. Select any program you no longer use and click Uninstall.

  

Pay special attention to trial software, old games, and manufacturer-installed bloatware — these are common offenders on systems where the computer is slow.

Method 2: Scan for Malware and Virus

Malware is a silent performance killer. If you are wondering how do I speed up my computer and nothing seems to work, a malware scan should be your next step.

• Open Windows Security from the Start menu. Click Virus & Threat Protection > Quick Scan.

• For a deeper check, choose Full Scan. This takes longer but examines every file on your drive.

  

• Remove any detected threats and restart your PC.

For persistent infections, consider a second-opinion scanner like Malwarebytes. After removal, you should notice an immediate improvement in computer speed.

Method 3: Enable Storage Sense

Windows has a built-in feature called Storage Sense that automatically deletes temporary files, empties the Recycle Bin on a schedule, and frees up local disk space, all without manual effort. Enabling it is one of the simplest ways to speed up computer maintenance over the long term.

• Go to Settings > System > Storage. Toggle Storage Sense to On.

  

• Click Configure Storage Sense to set your preferred cleanup schedule (daily, weekly, or monthly).

  

• Enable Delete temporary files that my apps aren't using for maximum benefit.

You can also run Storage Sense manually at any time by clicking Run Storage Sense now on the same page. This alone can recover gigabytes of wasted space and help speed up my computer noticeably.

Method 4: Update Your Windows

Keeping Windows up to date is often overlooked as a performance fix, but Microsoft regularly ships patches that boost computer performance alongside security improvements. Outdated systems also carry driver conflicts that cause slowdowns.

• Open Settings > Windows Update. Click Check for updates and install all available updates.

  

• Go to Advanced Options > Optional Updates and install any pending driver updates.

• Restart your computer after updates complete.

Staying current is especially important on older hardware — manufacturers often release optimized drivers that meaningfully improve computer speed without any additional cost.

Method 5: Upgrade Hardware

If you have tried all the software-based fixes and your machine still struggles, it may be time for a hardware upgrade. Two upgrades deliver the most impact for users looking to speed up an older computer:

Add RAM

RAM determines how many tasks your computer can handle simultaneously. If your system has 4 GB or less, upgrading to 8 GB or 16 GB is one of the most cost-effective ways to improve PC performance. You will immediately notice smoother multitasking, faster browser performance, and fewer freezes.

Switch to SSD

If your computer still runs on a traditional hard disk drive (HDD), switching to a SSD is the single most transformative upgrade you can make. SSDs have no moving parts, which means data is accessed almost instantly. Boot times drop from minutes to seconds, applications launch faster, and the overall system feels dramatically more responsive. This is widely considered the best way to speed up computer hardware for the money.

Conclusion

From removing unused apps and enabling Storage Sense to upgrading your RAM or switching to an SSD, there are proven methods at every budget to speed up computer performance and get your system running like new.

For the quickest and most comprehensive results, 4DDiG Partition Manager's Windows Clean function handles junk removal, disk optimization, and system cleanup in one place, making it the go-to computer speed up software for Windows users who want fast, reliable results without the guesswork. Start with the quick wins today, and work through the deeper fixes as needed, your faster computer is closer than you think.
