I can say with absolute certainty that (at least in America) reinstalling Windows does NOT void your warranty (despite what any rep may tell you), and selling you a device with a problem they assured you didn't exist is fraud.
I would return the laptop for a refund (regardless of how long you've had it), and if they refuse to take it back (which they likely will), file a small claims case in NC (I know, not necessarily an option depending on where you are). They may try to argue that you 'agreed' to arbitration, but because they misrepresented the quality of the device, you can argue that agreement was 'signed' under false pretenses, and isn't legally binding.
I'd also post recordings of your support calls online if you have them, or call back and record new ones if you don't. Posting those online does not run afoul of the broadcast laws which apply to phone recordings, and recording calls with only one party aware is legal in all but 11 states, and everywhere once they tell you they're recording the call.
I'm doing the same damn thing with the tech companies that screwed me over, so I made sure to do my homework.
