There are a few common things that can cause slowness on your computer or network — this includes too many applications running on your computer at the same time. These applications are triggered to launch and run on every startup. This situation is easy to fix if you know how to make adjustments to your system.
Another common reason: the storage device (hard drive) has slowed down significantly from when your computer was first purchased. However, with proper tools, this can be detected and adjusted.
Another possible reason: your computer has malware running on it. Using a reputable anti-malware software agent is highly recommended. Please note: not all antivirus /anti-malware software tools are equal. Some are great but some are very ineffective and can make things worse. We have years’ of experience of knowing how to detect and repair slow computers.
