High Memory Usage Problem

Hi guys, new around here. Hopefully you guys can solve my problem

Several months ago, I re-installed Windows because of an unknown error that prevented me from starting it normally. Then everything works fine. But about a month after, I started to experience the "Close Programs to Prevent Information Loss. Your computer is low on memory." error. I googled for some solutions, they said that I need to increase the virtual memory that's going to be used and I did, but it didn't solve the problem, it only helped. It allows me to do everything normally but requires me to restart my laptop after about 3-4 hours usage (where the error message pops up again and everything became so slow). More recently however, the problem occurs again, but it's much worse. I can't run windows normally just because I have the problem every time I launch it normally (and I really can't do anything other than to force restart with the power button), and running windows in safe mode is the only way (it even lags in safe mode).

Here are some screens of the task manager in safe mode (with networking):
I took the following screens with no application running.

(The CPU usage fluctuates between 1-13%)

Here are the running services

And this is the Process tab again with Google Chrome running (the only tab opened in the browser is the Create New Thread tab from tomshardware)

(With Chrome running, the Memory usage is rises to 1.50GB)

I think the problem is the RAM usage (which I have only 2GB but something is overusing it), but I don't know what caused it.

Here's my specs (as told by systemrequirementslab):
