How to free up RAM on my PC?

This problem is not related to your Laptops RAM, so I suggest you to please do clean up of your Laptop, I mean you open the my computer icon and the you can see the C drive, right click on the C drive and then go to the properties option and then do the disk cleanup process, it’s hardly takes 15 minutes and after this its provides you a good speed and some free space, so do this process, I think after doing this your game software easily run on your laptop, another think is that please do this disk cleanup operation in every month because its gives free space to your computer system memory. Other way is the defragment process and also removes the temporary files from your computer system. It’s very beneficial for your PC or Laptop.
