Since I have rechecked and noticed that it is not a disk space shortage, then the problem should not be on the disk but the RAM. Even basic tasks like opening up a Word document can be slow if you do not have enough RAM. You can check RAM usage in task manager by right clicking on the taskbar and selecting the task manager option. You will be required to click on the Performance tab of the task manager. Here, you will be able to graphically view how much RAM on your computer is being used. If the RAM is being over-utilized, you will have to consider upgrading your PC with more RAM.
