if ur using a laptop, its probably due to it overheating really fast
try getting gamebooster and simply keep ur computer or laptop cooled off

i use to actually put ice packs on top of the cpu when i leave it on overnight

Using the integrated Intel gpu? Yes? Go buy a cheap low-end card from Nvidia or AMD and witness wonders.

Gamebooster, Defrag computer.
