Run a Memory test and check for any faults in your memory.

Two times I had an issue like that. Once I had a bad stick of RAM, but this caused restarts at random times and data corruption. The second time, a bad video card which would not even allow the PC to get past the Windows loading screen.

Because it restarts when you join the BF4 server, I'd tend to think it's an issue with the video card when the game graphics processing starts. Could also be a psu problem as the video card demands more from it.

Hi 'VeTeRen ThoR'
I had the same problem with BF3 twice and it turned out to be a problem with 'PunkBuster both times'. I solved it by deleting everything that was connected with 'PunkBuster', 'BF3', 'BF4', and 'Origin' and then reinstalling everything from scratch. If this is the problem, then when it shuts down, you should get a notice (in a red bar along the bottom) indicating that the server kicked you off or a 'time-out' error occurred. Hope this helps.
