Microsoft Windows 10 (64-bit)

On startup I get the following message:

 

'The followng product information programmed into system board is missing or invalid-
System board (00A) System Board CT Number"

 

I have tried to retrieve the CT number by hitting 'Esc' on startup, then F1. It gives me a product number, serial number, Build ID etc but for 'CT Number' it simply says 'CT Number : HP'

 

Is this an error that will effect my laptop's performance?

If not, what is suddenly causing my laptop to work ridiculously slowly? Have run all firewall scans, defragged, downloaded appropriate updates to software, what more can I do to improve speed/performance please?
