My RAM usage doesn't exceed 70% even if I push it

[Makam E Mahmud]

Hello,
I have an Acer Aspire 3 A315-23 which I bought 4 years ago. It has 8 GB RAM from which 2.1 GB is hardware reserved for the iGPU. I didn't have any kind of major problems in the past 4 years. Recently, I have been having some problems. On 11th July, 2024, my laptop started having BSODs from nowhere. I was using Discord & Facebook on chrome. Just 2 tabs open and in the background Spotify was playing music. Suddenly a BSOD. I thought maybe a fluke, I restarted, another BSOD. And then another, and another. It goes on and on for like 3-4 BSODs' and then it stops. I go to my event viewer and see the 1st attachment error. So I thought o google about it and I got nowhere. And after my system came to a stable state, now my RAM usage doesn't exceed 70%, maybe 71-72%, and at that stage I cannot open any other apps, everything becomes unresponsive. I can only open task manager and shut down the process that's hogging RAM [in this case Chrome] and after that the system feels like nothing has happened. I literally cannot open Facebook & reddit at the same time because it will make my RAM usage go 70%+ and the whole laptop will freeze. I need help regarding this issue if someone has any experience with it.

Thank you for reading.
