Thank you for contacting Intel Customer Support.
In this case, what I recommend is to download and run the Intel® Processor Diagnostic Tool to see if there is any issue with the processor.
In regards to the game crashes, the Intel® Core™ i7-5820K Processor doesn't have integrated graphics; therefore, if you are having issues while running a game you may want to contact GeForce Support, as the graphics are 100% on the video card side.
Something to consider is that since the processor doesn't have integrated graphics, you are not required to install any driver to make the processor work.
Hope this information helps.
