Battlefield 3 randomly freezing during multiplayer, needs hardreset ?!?!

Well sorry but you really did not read my initial post.

I have been trying for weeks maybe even months with numerous different methods. I have been trying with my old rig and my new rig and I have been using my whole setup for very intense processes not only gaming including Vray, MentalRay renders, all sorts of simulations, 3dMax etc etc. Again, "not a single issue". To be more spesific (for your %100 utilization idea) I know I left my PC on for 15-20 or so days to render stuff nonstop with full CPU affinity and full ram allocation( this is when I purchased a better cooler for my CPU). No overheating, no crash, no random resets, no power failure, no nothing. I ran benchmarks, tried many different methods to see if there is any sort of failure. I have not spotted a single hardware failure. Like I said back in the days ( I do not know the spesific version of BF3) I reduced my sound quality to cd quality via control panel and it fixed the problem for a while. But I can not accurately tell what happened after, It all started again and still is happening.

I believe you assume that I tested this and that and started posting here which I understand but trust me it really is not the case. I am well aware different software use hardware in different ways but again I tried a lot of stuff and I mean a lot. 

Both my old ram and new ram were tested with memtest etc and no problems whatsoever. I have tried realtek drivers from ASUS website for my motherboard spesific drivers which is P6T. And yes I also have tried drivers from Realtek's own website and downloaded PB from punkbusters own website as well. I also tried re-installing, uninstalling and re-installing PB thru "pbsvc.exe", still no progress, still freezing after 15-16 minutes. I tried a variety of videocard drivers both for GTX285 and GTX670. It did not help at all. I have also made a research and NVIDIA guys even say that the current driver version (314.22) is the least problematic for BF3 which I am currently using.

I also tried what was just suggested about reducing the CPU allocation to 1 instead of all cores. I did it the way it was suggested and I also tried another method where I set  BF3.exe affinity to a single core. Game ran extremely slow in both cases on low settings and again 15-16 minutes, same freezing, same problem...
