I don't know much about computer stuff, but my old computer used to not like gw2. How old is your computer and what are the specs on it? Are you using the 64 or 32 bit client thing? You can also try to repair the client. Google repair client gw2. https://help.guildwars2.com/hc/en-us/articles/201863008-Repairing-the-Game-Client

Repairing game client worked for me.  Thanks for reposting the steps
