In order to make your computer go faster, I recommend you uninstall all unnecessary applications. You can do this if you go to Start > Control Panel > Uninstall a program, select the software you want to remove and press Uninstall. After that, run a registry cleaner from the database of Software Informer to make sure that there are no leftover registry keys in your system. Also, I suggest you update all drivers of the computer. You should find the latest drivers on the PC's manufacturer website. After that, go to Start, type msconfig and open the utility. Click the Startup tab and uncheck the boxes next to the applications you don't need to start when you open the computer. After that, click Apply and then OK. Also, in order to make your computer go faster, perform a full system scan using your security software or another similar antivirus and run a disk cleanup. You can use Google search engine to find additional guides and tips that will help you improve the performances of your computer.
