it restarts my whole computer just as if i hit reset. ive been using cpuid to monitor, just game for 20 mins and exit and look at max temps. both gpus and my cpu have never risen above 45c that i have seen. its not just arkham now though, it hapened in crysis also last night. tonight im going to make sure my drivers are updated, sure they all are though and maybe plug my surround sound into another outlet. maybe its pulling too much power and causes the reset. any other tips would also be great.
