I want to make my pc speedy

The best solution to speeding up your computer’s performance would be to buy higher memory (DDR1, DDR2, DDR3) than what is already installed in your computer. Another trick to temporarily increase your computer’s performance would be to close any programs that are running in the background of your computer that take up a large amount of memory.
To do this you will have to open your Task Manager which can be done by pressing the Alt+Ctrl+Delete keys at the same time. Another way of accessing your task manager would be to right click on your task bar and click on Task Manager.
When you have accessed your Task Manager, navigate to the Processes tab, which can be found near the top of the application. Here is a Image of what you should be looking at.
With the Task Manager you can view all programs that are currently running on your computer.
To increase your computer’s performance simply look for which program consumes the most memory, right click on the name, and then click on end process. This process ends the program and the memory of the program that was ended will be available for use can which in turns slightly increases your computer’s performance for the time being. One thing to take note of is that you should never end programs that are listed as “SYSTEM” as they are needed for your computer to run, ending programs that are listed as “SYSTEM” may cause your computer to crash. When you have accessed your Task Manager, navigate to the Processes tab which can be found near the top of the application. Here is a Image of what you should be looking at.
