Hello, can anyone help me figure out this problem and how to fix it. Anytime I put my laptop to sleep and wake it back up, when I go to play a game, any game btw, the clock speed of my GPU won't go past 405 while in the game itself. If I pause the game, go to the main menu, or anything like that the clock speed will rise to it's normal 1019 but as soon as i go back to playing it drops right back down to 405.

The only way I have found to fix this issue so far is I have to restart my computer every time I want to game now because of it.

I am using a Asus G750JM with the GTX 860M my drivers are currently 340.52. This happens weather the laptop is plugged in or not.

Not throttling that is for sure. You can trust me on that. When it is like this and doesn't want to go past 405 the temps usually stay in high 50s or low 60s. The hottest my GPU or CPU has ever gotten in this laptop so far was mid 70s

Like I said, this only happens after I wake my laptop up from sleep.

Could it be a driver issue? Since his asus has one of the best cooling solutions on a laptop.

Power saving feature, the GPU will downclock when in a idle state to save power and keep heat low, will only ramp to the rated clock speed when required to do so.
Same for the processor if you give it a look, will downclock to 800-ish Mhz when in idle and only work full power when doing tasks that require so.

what's your windows power plan on? Balanced? If so then up it to high performance and see if that changes anything.

You don't need the CPU and GPU running at top speed when idle, do you? Having those chips downclocking when they are not required to perform any heavy task reduces the power consumed, heat produced and lenghtens the lifespam of them.
You only need them running at top capacity when you are gaming or using a heavy software, the CPU and GPU will ramp up just then.

:/ Right. Disable the sleep states from BIOS for the CPU and set the max performance in the power plan for windows and in the Nvidia control panel.
However, just avoiding putting the laptop into sleep mode should be good enough to avoid the issue, right?
