What is causing to overheat/freeze during Steam Game play?

Now the heat is actually generated by the CPU and GPU in my pic is a rough idea of how the cooling is set up albeit in a Toshiba.

I am now wondering just how old is the machine - and sorry if you have said so already but I cannot see it - I am now thinking hard drive and RAM perhaps causing this freezing both are easy to test for but if the machine is new then most likely still ok - though not impossible that either could have gone or be going south already.

Hmm well like I said the battery volts and the rest of HW Info looks fine. The 59C of the CPU is within limits in my mind for running games as the Tjunction for that CPU is 105C Intel® Coreâ„¢ i5-3210M Processor (3M Cache, up to 3.10 GHz, rPGA Specifications

Thinking a little left field I am wondering what updating the HD graphics might do and get it from Intel not the Lenovo site. I have an Asus ROG laptop that runs the latest Intel graphics and they are brilliant even compared to the NVidia GTX860M I have on board too.
I am pretty sure this is the site you need https://downloadcenter.intel.com/dow...10-3rd-Gen-BYT-

Looking at the first photo in #11, I've seen a number of Notebooks where the finned part mated/fitted to the fan housing was plugged up and blowing out with compressed air didn't unplug it. Most times there were fine-haired pets in the house.

Yep mate that is why I posted the stuff in post #7 and it came up clean if the cleaning process was followed that I use with those chinelle craft wires and while blowing with the air at the same time

Well not really I thought it would be the cure to be honest as the Intel graphics on my Asus is perfect but I guess it is a much later version of their graphics.
