Is your computer taking a long time to load? Many users face this problem. A slow computer can make everyday routine tasks a hectic one. At that moment, you want your PC to be fast and smooth, whether you’re using it at work, at school, or just having fun.
Before troubleshooting, you may want to test how fast your computer is to get a clearer picture of its current performance.
Fortunately, things can be easily accelerated by some steps easily.
Tips to Speed Up a Slow Computer
Below are simple and effective tips to help you troubleshoot and improve your PC’s performance.
1. Reboot Your Computer
Rebooting your PC may seem like a useless and straightforward act, but it also cleans temporary files and resets background tasks. It may be helpful to restart your computer, especially if it has been running continuously without interruption.
2. Close unwanted apps
Unwanted apps can slow down the whole system. Look at what is open in your taskbar or task manager. Shut down what you are not using at the moment. Your computer will be less cluttered, with memory to concentrate on the essential things.
If closing apps helps only temporarily, it may be useful to understand how Windows uses virtual memory when RAM fills up, especially on a PC with 16GB of memory. Not sure what to close first? Some apps use considerably more resources than others, so it helps to identify which apps are slowing down your computer before you start uninstalling things.
3. Turn Off Start-Up Programs
Some programs automatically launch when you switch on your computer, even when you are not using them. These can increase your boot time. To prevent it, press Ctrl + Shift + Esc to open the Task Manager. Then turn off all these programs.
4. Free Up Hard Drive Space.
Performance can be compromised by low disk space. Free up hard drive space by clearing out old documents, deleting unused applications, and emptying your recycle bin. There are also built-in utilities, such as Disk Cleanup on Windows, that can be used to delete junk files without damaging them.
5. Malware Scan
Your computer can be slowed down significantly by malware. The solution to this grave threat is to ensure that you have an updated antivirus and security software in your system that is properly functioning or to seek professional help.
6. Update Windows to the most recent version
Ensure that you are using the latest system and drivers. Updates related to speed and security will be regularly included in Windows Updates.
Before spending money on new hardware, check how old your computer is and whether the rest of the system is still worth upgrading.
7. Hardware Upgrade
In some cases, upgrading the components of a computer is the only sure method of making a slow computer faster.
- Increase the RAM to help your computer run multiple applications without difficulty.
- Upgrade to an SSD (Solid State Drive) if you are using an outdated hard drive. SSDs can be significantly faster and can provide a substantial benefit.
8. Download Lighter Software
Heavy apps can bring down an older PC. Attempt to use the lite version of the programs or apps that are less demanding. E.g. replace Chrome with a lightweight browser such as Edge or Firefox.
9. Modify Visual Effects
Performance can be brought to a crawl by fancy animations and shadows. To disable them, open System Settings> Performance Options and select the “Adjust for best performance” option.
10. Hire a Pro
When you have done all that you can, and your computer remains slow, it may be the right time to consult the experts. Whether online or on-site, our professionals at Geek on Site will be able to diagnose the actual issue and resolve it quickly.
