Hi, randomly and only on certain games my computer starts to freeze up. The game goes to about 5fps and my computer freezes. Until I close the game. This happens at random intervals, maybe after 30 minutes of playing or 4 hours. I noticed it happened a lot on rust, blackops 4, apex legends, and some others. I noticed that the cpu usage will be at 97% when this happens. I cannot find a fix anywhere, I ran a bench mark through performance and all of my parts seemed fine. I am running on windows 10. Here is my specs:

GTX 970
intel i7-6700k
Corsair 16gb ram
asus z170-a lga 1151 ddr4 motherboard
corsair 850w power supply
 
Many games will cause 4c/8t cpus to be at/near 100% usage, so that alone is not really significant, nor does it imply cause/effect.

Let's first see if your temps are seemingly under control.

Install/run HWMonitor, which will allow real time monitoring of core clock speeds, core and package temps, core voltage, etc...

Then install/ run Intel Extreme Tuning Utility, select "Stress Test" , and then "CPU Stress Test", and then click on 'Start Testing"...(default 5 minutes is fine, or you can run it 10 minutes to simulate a gaming load)

Note temps achieved while test is running; if 65-75C, temps are not an issue. If temps hit 100C, you are throttling due to cooling (lack thereof).

Is your CPU overclocked?

Is your cpu cooler a conventional sink/fan, or a fluid pumper/AIO affair just 'waiting to fail'? (Bias alert!) :)

If all that looks ok, with no browser open, no scans or downloads occurring, etc.,what CPU usage is being displayed in task manager? (my own 7700K with all-core turbo of 4.5 GHz hovers around 1-2%, and 3% with Tom's Hardware Forum open.)

I ran the stress test for 5 minutes and the highest cpu temp recorded was 71C. My cpu is not over clocked, and I have a corsair H60 cpu cooler. With just browsers opened about 5% of the cpu is being used.
