You may want to consider replacing the 500 GB mechanical hard drive with a better performing 500 GB solid state drive (SSD).
After you replace the drive, you can reinstall W8.1 for free by downloading the plain W8.1 64 bit ISO file from the link below.
Download Windows 8.1 Disc Image (ISO File) (microsoft.com)
Use the Microsoft tool that I zipped up and attached below that you will need to transfer the ISO file to a DVD or USB flash drive so that it is bootable, or you can use a different free utility such as Rufus.
After W8.1 has completed installing you can install the drivers and available software from your notebook's support page.
