Windows constantly showing "Low Memory"

I have had this computer for the longest time and been playing the same video game (Garry's Mod) for a long time. I have recieved no memory low notification or had the game crash in the process of it loading.

The problem is, my computer keeps on notifying me with "Low Memory" which is constantly minimizing my game and crashing it. I have never experience this problem. Can someone help please?

Will check all of these things mentione. Will get back to you guys soon.

Low Memory warnings rarely mean a shortage of RAM. Such shortages rarely cause any problems other than poor performance. More likely it is due to reaching the commit limit because of a memory leak or a too small pagefile.

It could also mean a 32 bit process is reaching the limits of virtual address space availability. That is an application problem and there is little to nothing a user can do about it.

Well this problem never happened before. This problem started yestarday out of no where.

Everything in the computer is very slow. When im accessing a website such as sevenforums.com, it takes 60 seconds for it to open while before this issue happened, it took just 12 seconds. Anyhow, here is the image requested by "AddRAM"

This is everything without my game (Garry's Mod) running. With it running, there is low memory and often crashes.

How's you page file looking?

Im not exactly sure what that is (precisely). However if you want me to take more screenshots, i can do that for you to check out how my system is.

Ok so i followed all the steps on the website you provided me with.

Before setting the page-filing to automatic, it showed that the total paging file size for all drivers was 512 MB. I have a 4GB RAM and now it shows what the screenshot displays.

However there is no change with the result. The slow performance of my PC is still persistent
