The Resources frequently get maxed out | Tried all the available solutions in other forums

Hello!

My website frequently gets halt down and does not respond. It is because of the following two resources always being maxed out in such times.

 

1. Memory Usage

2. I/O Usage

 

I have attached the screenshots. The breakdown comes every few minutes and lasts for some time. It is driving the traffic away from my website. I have also added the memory limit in Wordpress Config php file. Please suggest the solutions.
