Of late, I noticed that my PC's overall speed and responsiveness have slowed and files and programs take longer to open or launch. I can actually hear the tick and buzz as the hard drive struggles to launch programs or open large files. Even though I regularly run my disk defragmentation tools on my PC, I find my programs still take a while to launch and when they finally start up, they run slowly . Wild Boar says that we need to get a disk defragmenter to re-aligns the hard drive files to recharge PC speed and performance. With this we can do a regular disk defragmentation for our computer to ensure that it runs smoothly from now on. It can be quite frustrating to have a PC that is sluggish in its performance.
