There are plenty of things that can slow your computer down.
Among other things, there are unwanted programs (known as “bloatware” or “crapware”) that can bog down your system resources. We’ve seen some computers with dozens of these programs installed! There’s also dust that can build up in the ventilation system. This dust can block the vents and cause heat to build up inside your computer, eventually causing your computer to slow down and at some point fail entirely, burning up the components. In laptops, especially, it can be extremely difficult to clean this dust out properly.
Not to mention viruses, malware, spyware, and possibly even aging and failing hardware.
The Computer Cellar’s technician team are experts at diagnosing and fixing these issues, by inspecting your computer’s software and hardware thoroughly, testing components, and helping you make changes and improvements to optimize the performance and behavior of your system.
