A reboot couldn't hurt. These errors are very common in battlefield games I saw quite a few in the BF1 beta, but I haven't seen one in bf4 for a while. Many things can cause it, from my experience pushing things too far is often the culprit. Try lowering your gpu overclock a bit and see if they stop, turn down in game settings a bit particularly MSAA or if you have resolution scale set over 100.
If that doesn't work try reinstalling directx for bf4. Go to C:\Program Files (x86)\Origin Games\Battlefield 4, click on the _installer folder, click the directx folder, click the redist folder, scroll down until you see DXSETUP.exe, run that and go through the installer.
Let me know if none of that works and we can try a user.cfg file.
