How software makes computer slow?

Answer 1

This is a very hard question to answer because there are a lot of factors that can contribute to a computer running slow. I'm not a computer technician but in my estimation from my experience with computers the most likely reasons would be:

1. Spywares or Viruses

2. Programs running in the background eating up your computer resources.

3. You are running programs too heavy for your computers capabilities, thus overloading it and causing it to run slow.

In 90% of the cases its Spywares or some Virus. You can sometimes spot if you have a spyware eating your memory from the Task Manager and closely surveying what programs are eating the most resources and if they are indeed something you yourself have installed or something unknown.

Answer 2

Things that make a computer run slow are things like viruses and too many files. Other things like slow internet and too many programs running at once are all things that can make your computer run slow.

Answer 3

Software of any kind will use computer resources. If it is running, either as an open window or a background process, it will be using RAM space and Processor time. When too many programs are demanding these resources, the coputer will be forced to run more slowly to complete all of the requested tasks. Even if the program is not running, it still can have a small impact on your system, since it uses Hard Drive space and creates extra registry entries which the copmuter system must search through when looking for other items. This effect is very small, but but can become a problem if your system becomes bloated with this extraneous information.
