Battlefield 4 - PC - always crashes

I got this as well, it's been already 2 months...always the same thing, but it's based on "fortune"...sometimes I can play full matches one after another, sometimes I join a server, play for about 5 minutes, then get CTD with Windows error popup. Now, reading the details of the problem, what I see that is important is "APPCRASH ---> bf4.exe ---> nvwgf2umx.dll". Now, it's obvious that the OS is trying to tell that the problem is generated by the video driver (in fact, on my DXDIAG, I can see that one of the many "main" video drivers is the nvwgf2umx.dll), but then again I got no errors on the DXDIAG, and in fact all other games are working fine. Any EA advisor will always tell u the same useless things: "repair the game, disable Origin overlay, disable anti-virus, disable firewall"...no really, are u serious? Look at these forums, plenty of people with this problem, people that aren't stupid and that already tried to format, update/change drivers and so on, and still the puslisher (EA) can't comunicate to the developer (DICE) to try to replicate this mess on their own PCs and MAYBE find/work on a solution? Isn't this what all your job is about?

But anyways, here are my specs:

CPU Intel Core i5-2500k @ 4,0GHz (overclocked)

GPU Asus GTX 670 (stock)

RAM 8GB DDR3 @ 1866MHz (stock)

OS Windows 8.1 x64

I have the game since december 2013, and never had this problem until maybe the "famous" first "netcode" patch (which upgraded the servers tickrate from 10 to 30 hz). I tried both Windows 7 x64 and Windows 8.1 x64, nothing changed. Tried different versions of GeForce drivers, nothing changed. Last note to EA: I paid real money for "Battlefield 4 Premium Edition", can I expect a "premium" support from you?
