Needs an Overhaul

That would be my almost 4 year old laptop. It looks like its hard drive tools are in shambles because it's been making some funny noises. It's also been super slow lately that I don't even want to use it sometimes. I *think* it's still in good shape given that it's quite old already so I don't want to replace it with a new one. I have a hard time parting with my stuff especially something that I'm so accustomed in using. My other laptop was replaced after 7 years just because it was so noisy already. It was also quite heavy so I decided to replace it with my current one. Guess what? That other laptop stayed with me until early this year because I couldn't part with it. Only when my brother asked if I had a spare laptop that I decided to say goodbye to it. At least I know it's in good hands. Anyway, I'm hoping that my current laptop only needs some defragging or probably an overhaul to work faster. I really don't think it needs to be replaced....as of yet.
