Hi JazzerStone,

Does this happen when using a specific app or performing a specific task? You can start your Mac up in safe mode to see if this continues to occur? Safe mode prevent certain software and processes from starting up, checks your startup disk and clears out your cache. This can help when experiencing unexpected issue and it will help isolate this issue a bit more.
