Okay this is my first time posting, I think I'm doing it correctly. I've gone through the steps at this location: https://www.techspot.com/vb/topic44306.html CPU: i7 920 @ 2.67 GHz MB: MSi X-58 PRO-E RAM: 3x CORSAIR 2GB 1600MHZ GPU: 2x EVGA GTX 260 PSU: Rosewill 1000W OS: Windows 7 Enterprise -Problem- When running BF3, about 30-45 minutes in, it all just freezes, no force restart or input recognition. giving about 2 minutes on this idle screen, nothing changes, need to hard reset. Attempts to fix as per the above link: 1. Updated nVidia, then to Beta, then back to March drivers, same problem recreated itself each time, no difference. 2. Event log shows the title of this thread multiple times at almost every crash. 3. I have a minidump. 4. Installed speedfan, and all voltages are fine 5. first thing I thought was overheating, relocated case, more fans, temps not going above 60c for intense BF3 playing. (before crashing, my system would get to 75 sometimes for short periods without problems) 6. RE the recent changes, I checked the system restore and the points I have wouldn't help, there aren't any before the crashing began (about a week ago) 6(again). I ran Memtest like the instructions say, took quite awhile, zero faults. (I was half asleep, my girlfriend read the monitor and said something close to that) -Bottom Line- I hope I didn't miss anything. I'm doing the 0 page allocation and defrag right now, but I don't think that'll be a problem, this computer is on a routine defrag weekly. I'll update if it returns anything out of the norm. I appreciate any assistance!
