After recent update HP Laptop gets stuck shutting down or resetting and overheats

So I have a HP Elitebook 725 G3 and up till now it has been acting fairly well with no major issues. However after the most recent set of updates every time I have shutdown or reset it has got stuck on a blank screen and the processor is running at 100% given the amount of fan noise and the fact that after a while the system shuts down because of an overheat issue.

Any pointers to what might be causing the issue would be much appreciated.
