Another thing that may be worth trying: run a Clean Boot: http://help.ea.com/en/article/how-to-clean-boot-your-pc/
This should ensure that no programs are interfering in the background.

Disable Mantle if you have it and try Direct X, Turn OFF Anti-Aliasing Deferred in video card settings in game. If you have page file turned off then turn it back on as this can make errors even with 32gigs ram.

Others have said if they uninstall MSI Afterburner issues / crashing is stopped. So if you have this installed remove program and test BF4. Also look at other programs as Fraps,EVGA Precision, Geforce experience, be sure to turn off the streaming function that is enabled by default ,Raptr, RivaTuner , ASRock eXtreme Tuner, Steam, Skype, aero ,Overwolf extra program in teamspeak and xfire are known to make issues as well. And I am sure more programs not in my list yet turn one off at a time and test BF4. Since last patch more programs now give issues :/

Uninstall the HD Audio Driver from the video card driver install add/remove programs. This silly thing makes issues in BF4 for some. Reboot then repair BF4 to be safe.

Another thing to try is re- install origin only.

1. Uninstall Origin completely from Windows Control Panel.
2. Reboot your PC. This is important to clear out any lingering registry files or directories.
3. Download the latest here: http://origin.com/download
4. Install Origin You should not be prompted to update.




If all this fails to fix it then try this...

BF4 folder in my documents holds game configs and screen shots even if BF4 is installed on different drive. When you uninstall BF4 it does NOT remove this folder. So when you install the game again you can still have the same issues. Even if its not a new install it is still worth trying as the game cfg could be mucked up.

1- Go to my Documents and remove BF4 folder place it on your Desktop or trash.
2- Be warned you do have to set up your in game settings again.
3-Repair BF4
4- When done go test your game. If it fails reboot your PC and run repair game again and test BF4.

I found this guide earlier on google but nothing helped, I have no more ideas except redownloading the game again but I doubt it'll work ...

Whats your event viewer say any errors when trying to load BF4?

If you need it

1. Click Start, and then click Control Panel. Click Performance and Maintenance, then click Administrative Tools, and then double-click Computer Management. Or, open the MMC containing the Event Viewer snap-in.
2. In the console tree, expand Event Viewer, and then click the log that contains the event that you want to view.
3. In the details pane, double-click the event that you want to view.
   
   The Event Properties dialog box containing header information and a description of the event is displayed.
   
   To copy the details of the event, click the Copy button, then open a new document in the program in which you want to paste the event (for example, Microsoft Word), and then click Paste on the Edit menu.

There are no warnings/errors from the time BF4 was running. I already deleted the whole thing including Origin and now I'm in the process of downloading it again but it will take several hours .. I even tried reinstalling graphic drivers and starting the game with Outcome instead of Origin.

Did you try this as well ..

Before actually buying the game I was able to play on maxed out setting with constant 60 fps (vsync).

Crazy 😕mileyfrustrated: Almost sounds like a program on your PC doing this but I could be wrong did you try a clean boot to rule it out?

Yes, except I don't turn off my PC for weeks even months I just hibernate it so it was in the excat same state when I was playing the game just fine this morning and an hour later when DLCs completed downloading and immediately the game broke down. It's like one of the DLCs is broken.

After your done the d/l I would reboot the PC and then run repair game it could be due to no reboot of PC after the d/l
