I just built a new system, I moved all hardware FWD from old PC, only the Processor, Mobo, and Memory are new.
At this point I really dont think is memory related, I have swapped out each stick, and BS errors happen with either stick by their selves, or together. So far my first BS error always happens about 20 40 minutes into BF: BC2. I checked my CPU (35C 95F), and GPU (69C 156F)after playing BC2 after about 15 minutes and before any crashes. Usually when crashes happened after extended game play, it points to an over-heat factor, where hardware becomes unstable, but my temps are normal, so Im kind of baffled. I have tried three different drivers, two of which ran fine in my old PC, but usually if you have video driver issues, you get a crash soon after the game launches, not 20 40 minutes later. It doesnt load your system near as much, but I played BF2 for about 90 minutes with zero Blue Screens, its the only other game I have installed. I have MoH, which in MP uses the Frostbite engine, but have not tried it yet (not installed). I have run several HD movies with no BS errors. I ran 3DMark 11 set to extreme for an hour with no BSs, and I let Prime 95 run for about 3 hours with no errors.
While in BC2, I get a real quick artifact effect in my graphics, then an instant BS error. I instantly reboot, and after the 1st BS error my next BS will come after only 5 10 minutes in BC2. Once again this acts more like something is overheating, my case has a very clean install, just the GFX card installed on the mobo, all other PCI slots are open, two 120mm intake fans, 140mm blow hole, 120mm side-panel for extra GFX card cooling, 120mm exhaust, and my CPU is liquid cooled with twin radiators mounted externally. I have run the system with BIOS default settings, and memory timings changed to G.Skills settings (8-8-8-24). By default the BIOS wants to run memory timings of 9-9-9-25, set to either setting, I get BSs in BC2. I have powered down both of my external storage drives before attempting to play, still to remove all possible hardware out of equation.
Built on 5-25-11, and Ive never had any BS errors while on my desktop, so far only in Bad Company 2
