I remember having the same problems as you have tried different methods. Was closing all the background apps that were eating RAM. Tried to reinstall Windows hoping this will help. But the computer was too old and was lagging even to bet sites like https://www.u12x.com/แทงบอล/. That was the point where I understand that I need a new computer as soon as possible. And after a couple of weeks of working hard at different part-time jobs, I got a new computer and never had such problems in my life.
