Answer to "Why is my computer running slowly?"Hello, The important point here is, What is the operating system? As a new pc will have minimal programs installed things run smoothly. As time goes by and you install programs, the software companies deem their program is very important and will have the program set to start automatically (which uses up some resources). Even though you are not actually using the program. Over time the number of these builds up eventually slowing down your system. As so many are started , that you do not automatically need right away. What you need to do is to review start up procedure to disable auto start on programs you do not automatically need straight away. This does not mean to say that when you click on the program it will not start. It will work fine when you click on it to start in. It just means when you boot the pc it does not start it there and then. Let me know the so and I can try and guide you from there.
