Sorry bud, but your Chromebook is terrible for doing anything other than light internet browsing. You also said you can't add more ram which makes this even worse. Again, no good way around this except a better PC.
You probably don't have enough VRAM. You're probably pushing your graphics card pretty hard with shaders and a HD resource pack with it only having 1 GB of vram.
That's all I can think of considering how many solutions you've tried.
catmelonhat? the guy that gives every single submission a diamond?
also no, they're still able to browse the site, they just can't post anymore submissions. (and it doesn't say "banished" all over your profile if you're banned).
