You might need to clone your hard drive if it has one and clone it to SSD so that your laptop will perform faster.

Then you might want to upgrade your laptop's RAM and use RAM with more GB. However you might want to refer to YouTube tutorials on how to do it, but I was able to accomplish it in one try.

It is what I did to my laptop because I don't want to buy a new one. Now it is fast and I can even play GTA V if I wanted to.

Goodluck Ma'am.
