You can't (easily) fix a hardware bug baked into your computer by its supply chain and manufacturer.

The best solution is to buy a computer that is not affected.  That means no generic Best Buy or Newegg blue light specials.

I recommend getting a phone and/or laptop from Purism, "maker of security focused hardware and software."

Please note although Purism is partners with and takes payment in Monero, they will don't accept instamined shitcoins like Dash.
