IDK why you guys aren't seeing the Nvidia "Video Driver Crashed and is Restarting" popup, but what you are describing are the symptoms experienced after an Nvidia Driver crash - the GPU throttles to minimal performance until you reboot.
This crash usually comes from a GPU memory clock OC. In my experience all the G750 models can take the highest GPU frequency OC - slider all the way up, but the memory OC is more sensitive.
For the JH, here is where I am stable:
Whatever the default memory frequency is for your version of the G750, increase in 100mhz increments until you get the throttling behavior, and the back off 2-300mhz and that should be enough to allow stable running during long gaming sessions - if not drop it down another 100mhz at a time until it is stable.
It isn't the temperature that is the problem, it is the memory OC 🙂

no no i can overclock and not have any problem my oc clocks are noe 0997 mhz core and 6088 mem. our problem si we are using a modded vbios...and we pushed the core up to 350 mhz we literally started from the bottom 200 mhz 300 mhz on the core.. everything works fine for a little bit then we see gpu load drops to %50 and lose 20 fps for a few seconds and then it goes back up..so it keeps doing this back and forth. gpu z perfcap shows all gray so utility no power problems..and it's not driver crashing. if it i would never get over P5584 on 3dmark11 which is very hard to get with gtx 765m. dreamonic and I tried everything different drivers downclocking cpu changing tdp limits playing with master voltage...the card doesn't heat up it happens at 64 c 74c it happens every a few seconds..20 fps drops and then goes back up...
