    A 500W PSU for a GTX 960 is a little light. The recomended PSU is 400 W, your PSU has a maxmium load of around 475 W, which means that provies very little room for any other device. You also have a very power hungry CPU and after market cooler. This is a power supply problem upgrade it to 700W+ PSU or downgrade the GPU. – Ramhound Jun 17 '16 at 17:15

As @Ramhound said in the comments, your issue likely stems from your power supply not having the juice to supply the whole system.

CoolerMaster even has a calculator you can use to determine what you need from your power supply to run your system smoothly. http://www.coolermaster.com/power-supply-calculator/

See this site's chart as a reference to the power consumption of your video card:


700 watts is a good number to aim for when buying a new power supply, and 80+ ratings are definitely worth the few extra bucks.

If you intend to add more components to your computer in the future you may consider going even larger (800-1000W). This could be another graphics card (which will double the power consumption seen on the tomshardware page), more hard drives, etc.
