Bump, i got the same thing i was playing around 3 a.m. finishing off a few things when my server crashed and wouldn't let back on. All my friends can still play but im left stranded in skype listening to them play :(
This happens to me too, i noticed my CPU usage skyrockets to 100% and then instantly drops to 20% when the screen turns white. Now i just need to know how to reduce it >.>
