I have a similar problem with my ASUS GTX570. After spending the weekend trying various tests and benchmarks, I’ve come to the conclusion that it’s a combination of the GW2 + the Nvidia drivers..
I am currently in the process of rolling back the drivers (clean install each time), to try and find the most stable. I am currently on 304.79 but had a crash/freeze this morning. Next I am going to try a pre 300 driver (probably 296.10). I know the 300 drivers are suppose to bring better performance for GW2 but I’d rather have a stable machine and low fps. than it crashing randomly.
I also think the “brand” of card (i.e ASUS, gefroce etc) is a factor. I suspect each brand might be “stressing” the internal components (memory clocking etc) slightly differently. This could also explain why some posters say they have no problems with Nvidia while others are crashing randomly.
I should point out that having spent the weekend testing, I am certain its not my PC. It only happens when I play GW2. I can have nothing else running except GW2 and then it randomly freezes and I don’t even get a BSOD. On the few occasions I have had BSOD, the dump files have pointed towards the drivers.
Since your running a Geforce card not a ASUS, you might find rollback (clean install) your drivers to a previous 300 version is more stable? Personally I am not have much luck with them though. Other posters might be able to tell you a combination that works?
