An update: I found this solution on another forum and it worked for about 5 minutes then I just start crashing again. This is what I tried ( you need to backup a folder named DayZ. This folder is located in "C:\Users\{username}\AppData\Local\" The easiest way to get to this folder, is to open a random folder, and type %localappdata% in the address bar. Then backup your DayZ folder and delete the old one. After this, you can now launch DayZ and try to connect to servers again. ) this worked for 5 minutes then started crashing again.
