First off, it's really hard to wade through one GIANT block of text. In your reponses, please break the text into sentences so we can read them easier.
Second, this is most certainly NOT a new PC. This model was already on sale in January oif 2014 -- over three years ago! This is important because HP doesn't stock Recovery Media for older PCs like this, and you would have to check with these other sites to see if they still carry it: http://www.computersurgeons.com/ and http://www.restoredisks.com/
Third, from your description, it sounds like the AC adapter you are using is not the correct one for this laptop or it is faulty -- such that connecting the laptop to it introduces some king of power fault in the laptop.
Fourth, whatever source told you to change your refresh rate from 60Hz to 40Hz is a source you should avoid.
There are links for checking adapters, but you would have to be able to see the screen to use them, so there is no point in providing those links.
If it does, then it's possible that either your adapter is bad, or something in the laptop motherboard got shorted out -- neither of which we can diagnose or repair from here.
You would need to take your laptop to a PC repair facility and see if they have an AC adapter that will work with it. If they do, then we can discuss alternatives about doing a clean-install from scratch to get it working again.
