Lenovo Y580 graphics problems
I was lucky enough to record a crash in World of Warcraft which had been happening once an hour or so all night.. I was using NVIDIA driver 305.46 which I had downloaded from http://support.lenovo.com/en_GB/resea.... I don't believe this is a software issue because I had tried numerous other NVIDIA drivers, including 310 and 313 beta, with the same problems.
The Lenovo energy management settings at the time were set to 'Balanced'.
NVIDIA GeForce GTX660M (GDDR5 2GB)
Intel i7-3630QM 2.4GHz
8GB DDR3 RAM
Windows 8 64-bit
