Did you try running the onboard diagnostics yet? Restart your system and press the D key to enter, did you get any errors?

Reference: Mac startup key combinations

Then that tells me your system is likely overheating!

So it might be a simple case of cleaning the dust out of the fan blades and heat sink fins. I would also carefully dust off the logic board as well. In its self this likely won’t fix your issue but it should lengthen your systems run time as your logic board has a failing component or solder joint which will need to be investigated,

This should prove the boards temp is the issue or not. Let us know what you discover!

这个答案有帮助吗?
