Slow Computer, Windows Install, Repair, in Essex & Romford
There are many factors that cause a slow responding computer. It may be overloaded with too many programs, even if you are just using the computer for basic functionality such as web browsing and email.
When you purchase a computer they come with lots of trial programs such as McAfee antivirus, Norton online backup, games and programs. These can add on average 15 extra unnecessary processes to the computer. Even if you decide not to use these because you have your own antivirus program, or don't use them, some remain and continue to run even if uninstalled.
Overtime you may install and remove applications. Application entries/folders co-exist even after removal. These will contribute to a slower computer. To run multiple services computers require more memory usage, so not having enough RAM will not help. Other causes may be hard drive read and write error, (if hard drive is old it can take multiple read/write attempts). Fragmented files, (single files are broken into pieces and stored in different locations).
