HELP, BF4 stopped working

I've had a similar problem that I solved by disabling Anti-Aliasing. Maybe try it out?

This list can be posted for a lot of reasons. Perhaps you wanted people to spend time looking at your problem but you didn't want to spend the time yourself to explain it in detail. Perhaps you havn't mentioned your platform or computer specifications. Maybe your topic was something useless like "help" or "bf4". Anyways, this list will contain information on how to give more information or give you the solution itself. Hope this helps. 1. How to make a well made question:

• 1.1 Please write descriptive (also the subject line) so the right people find your question and knows what it contains.
  1.2 Tell if it has worked before, when it started not working and what did you do just before that!
  1.3 Post relevant log files, screenshots, descriptions, movie, dxdiag, exact error messages, and all other relevant information(like platform) – even if it’s stupid and obvious (there’s a lot of clueless people on the internet, we don’t know if you are one of them )
  1.4 Tell what you have tried in DETAIL and how you did it in DETAIL and what the results are, in DETAIL!
  1.5 Upload your dxdiag somewhere and link it: http://help.ea.com/en/article/how-to-gather-dxdiag-information/

2. Check for current outages and bugs:

• 2.1 Check the Origin server status: http://www.origin.com/us/status
  2.2 Check News and Official Announcements on Battlelog for outages and current problems.

3. Common questions:

• 3.1 Banned? Read this: - https://help.ea.com/in/article/information-about-banned-or-suspended-accounts
  3.2 Veteran status? This is gained from playing other Battlefield games. Play4Free, Heroes and 1942 is free to download and play and each give a veteran rank. Other games can be registrered at http://www.battlefieldbadcompany2.com/veteran. If that doesn’t work contact EA support. There's currently a bug for BF4 so if you don't have your BF4 entitlements / status you will have to wait until a fix is out.
  3.3 How to contact EA? Go to https://help.ea.com/contact-us . Fill in keywords then product, category and platform. Press ‘Find Solutions’ –>; ‘I Still Need Help’. Contact options will appear. If live chat/phone does not appear, it might be closed in your area at the moment and you might consider changing it to: ‘United States’ or something else in the language selector in the bottom of the site.
  3.4 Can’t access DLC/Premium? To find and handle your DLC right-click your game in Origin and click ‘show game details’ and scroll down to ‘expansions’
  3.5 Refund? You can do that under help --> history if you bought it within 24 hours ago, otherwise you will have to contact an EA Advisor at EA customer support.

4. Common mistakes:

• 4.1 Can’t find your game? Make sure you have bought BF4 and not just Premium. Make sure you are logged into the same account as the one you registered the game on.
  4.2 EA doesn’t answer you? Answers HQ is a place where users help fellow users, not a place where you can expect EA to answer.
