Did you check Advanced Power options in Control panel ?

 

[nico.schmolke]

Yes and did a stress test Nothing changes

I am downloading the Intel Cpu Diagnostic Tool

 

[CountMike]

Max CPU at 100% ?

 

[nico.schmolke]

it maxes out by 37%

 

[CountMike]

Should be set to 100%.

 

[nico.schmolke]

i mean in the power pan it is minimum 100% and Maximum 100% but in the stress test it is 37%

Been going on since January...Probably a bad sensor or a heat issue forcing it to stay throttled down.

 

[nico.schmolke]

cpu works fine on the 2015(year) version but not on the newer ones windows 8 7 is fine too

 

[nico.schmolke]

can this be an unsuported driver problem?
