Is your computer running slow? Find out how to speed up your PC and laptop!
Introduction
Your computer post-leasing runs slowly and you are increasingly annoyed by long program startups? You are not alone! Many users of post-lease equipment face this problem. Fortunately, there are several proven ways to speed up your computer and regain comfort without spending a fortune.
1. Check the amount of RAM
RAM is crucial to the smoothness of the system. It is in this memory that the computer stores currently used data and programs.
How much RAM do you need?
- 8 GB - the absolute minimum for Windows 10/11 and everyday use (browser, videos, documents).
- 16 GB - optimal for multitasking and modern browsers that can heavily load the system.
- 32 GB and more - if you're into games, video editing, CAD or virtual machines.

What kind of RAM to look for?
- For laptops - usually SO-DIMM DDR4 or DDR5; check if your laptop has free slots.
- For desktops - DIMM modules, also DDR4 or DDR5 (depending on the motherboard).
Why more RAM helps: because when the system starts running out of memory, it starts using the paging file on the disk - and the HDD is dozens of times slower than RAM. This causes the system to muddle.
2. Replace the HDD with an SSD - the difference is huge
If your computer is still using the HDD, it is the main culprit of slow performance.
Why is an SSD better?
- SSD has no moving parts → runs lightning fast.
- The system boots up to 5-10 times faster.
- Programs open in a second instead of a dozen.
- Less failure rate and quiet operation.

Which SSD to choose?
- SATA 2.5" - compatible with most computers (about 500-550 MB/s).
- NVMe M.2 - the fastest (even 3,000-7,000 MB/s), if the motherboard has the right slot.
Is it worth it, yes - this is the best upgrade you can do. An old computer after replacing an HDD with an SSD can get a second life.
3. Remove unnecessary programs and files - it really matters

An overloaded system runs slower. This is especially true for older machines. What's worth doing?
- Uninstall infrequently used applications (especially those that start with the system).
- Remove large files from "Downloads" and the desktop.
- Empty the recycle garbage can (yes, that matters too).
- Run "Disk Cleanup" or a tool like CCleaner (carefully and without aggressive settings).
Why this helps: Windows handles the disk and indexes files faster. Fewer applications = less load on CPU and RAM.
4. Limit the programs that start at startup
Many applications load automatically as soon as you turn on your computer, slowing it down by up to several minutes.How to fix this?
- Open the Task Manager.
- Go to the "Startup" tab.
- Turn off everything you don't need (e.g. Discord, Steam, Teams - if you don't use them every day).
Why it works: fewer background programs = more resources for you, not for apps.
5. Keep your system and drivers up to date
Contrary to what you might think, updates really speed up your computer - what to update?
- Windows Update.
- Motherboard chipset drivers.
- Graphics drivers (NVIDIA, AMD, Intel).
- BIOS/UEFI - if the manufacturer has improved stability or performance.
Why it helps: Newer versions better manage power, memory and processes. They also fix bugs that can cause slowdowns.
6. Take care of antivirus and security
Viruses and malware can:
- overload the CPU,
- surreptitiously consume the Internet,
- send data,
- install ads and scripts in the background.
What to do
- Scan your computer with an antivirus program.
- Scan with an anti-malware tool (such as Malwarebytes Free).
- Remove suspicious extensions in your browser.
Why does your computer run faster after cleaning? Because malicious processes often take up as much as 30-70% of CPU power!
7. Overheating = slowing down
Many people don't know this, but an overheating computer automatically reduces performance to protect components (known as thermal throttling).What to do?
- Clean the fans and heat sinks of dust.
- On laptops, perform cooling system maintenance.
- On desktops, improve air circulation and replace thermal paste.
Symptoms of overheating:
- computer runs loudly,
- laptop steams from underneath,
- games or applications suddenly slow down.

Summary
If your computer is running slowly - don't panic. In most cases, the problem can be solved at home:
- add RAM,
- install an SSD,
- keep your system in order,
- disable programs from the autostart,
- update drivers,
- check the system with antivirus,
- clean the computer of dust.
It's simple, and the results can be spectacular - the computer often speeds up as much as if it just came out of the box. If, on the other hand, the problem persists, take a look at our offer on post-lease laptops:
