What You Should Know About Driver Updating

There are numerous of frequent warnings and also other messages which you may get in the driver updating procedure, a number of which I've paraphrased and listed here as well as information on what you can do:

Windows requires a digitally signed driver: In 64-bit versions of Windows, you won't even see the above two messages because Windows won't let you install a driver that has a digital signature issue. If you see this message, end the driver update process and locate the correct driver from the hardware maker's website.

QUESTION: NVIDIA GPU maximum operating temperature and overheating

ANSWER: NVIDIA GPUs are designed to operate reliably up to their maximum specified operating temperature. This maximum temperature varies by GPU, but is generally in the 105C range (refer to the nvidia.com product page for individual GPU specifications). If a GPU hits the maximum temperature, the driver will throttle down performance to attempt to bring temperature back underneath the maximum specification. If the GPU temperature continues to increase despite the performance throttling, the GPU will shutdown the system to prevent damage to the graphics card. Performance utilities such as EVGA Precision or GPU-Z can be used to monitor temperature of NVIDIA GPUs. If a GPU is hitting the maximum temperature, improved system cooling via an added system fan in the PC can help to reduce temperatures.
