If your computer is still slow after trying to speed it up, then it’s time to consider some more advanced options, such as updating hardware components, such as the RAM or graphics card, or reinstalling the operating system. Additionally, replacing the hard drive with an SSD can greatly speed up a computer, as can installing an optimized version of your operating system. If you’re still having issues, then it might be worth consulting a professional computer technician to help diagnose and fix the underlying issue.
