Are you playing a game or using another very CPU and/or graphics card
application when this occurs?
If a Laptop, is the laptop sitting on a hard flat surface so that the fans

If a laptop and you suspect that the fans on the bottom have become clogged
I have found that I can such the dust out of the bottom fans with a vacuum
cleaner.
