Hi:

 

You installed an unsupported processor.

 

Below is the link to the product specs page for your PC.

 

https://support.hp.com/ca-en/document/c05273188

 

It can only run three Skylake 6th gen core processors. 

 

A 7th or 8th gen core processor will not work.

Oh thanks Paul

I checked that already, I thought they mentioned 6th gen cores due to the production date for the pc.

Is that clear no way to run 8th generation?

Thanks

You're very welcome.

 

No way a 7h or 8th gen core processor will work in a PC with a Skylake chipset.

 

The best you can do is the i7-6700.

You're very welcome.

 

Hopefully you will be able to use the processor in another PC one day, or you can always put it up for sale on eBay.
