This sound more to me as if the problem is malware, rather than a non-genuine one.
Boot to Safe Mode with Networking,
download and install Malwarebytes Anti-malware (free version) from http://www.malwarebytes.org/products/malwarebytes_free/ - UNtick 'Enable free trial of MBAM PRO' at the end of the installation - and update it, then run a full scan in your main account, and Quick scans in any other user accounts.
Delete everything it finds
ONLY THEN reboot to Normal Mode, and see what happens.
If you still get a non-genuine error,
Please follow this tutorial and post an MGADiag report - then we can see what the problem is.
Please also state the Version and Edition of Windows quoted on your COA sticker (if you have one) on the case of your machine (or inside the battery compartment), but do NOT quote the Key on the sticker!
Ignore errors produced when clicking on the Copy button - they simply mean that the tool could not create the backup files for some reason. The data is still copied to the clipboard for pasting to your response.
