PC stuttering and lagging so much after HP initializing BIOS update repeatedly after warranty ended

[Rilenixx]

So my son's warranty ran out 3 to 4 weeks ago.  We finally had it running efficiently after having the PC delivered on day one with the CPU liquid cooler not attached, a strange issue where the PC would turn on and the off and then on again everytime on startup among a half dozen other issues.  I was emailing a gentleman in the claims department named Victor and he offered me a chance to fully refund the PC.  I told him that was great but I was getting a double fusion back surgery and this PC was all my son had.  That for the time being the PC was at least operating and my son could still game on it.  I requested that instead of sending it in for full refund because my son would be devastated not having his PC and how he had only had it for a few months, that I would ask that HP extend the warranty to two years for us instead.  I am a single father and my son is handicapped and autistic.  This PC was all he had ever wanted and saved every last penny I had to buy the Omen 30L, I5-10600k CPU, Nvidia RTX 2080 SUPER gpu, 16 GB RAM, 1 TB SSD, 1 TB HDD.  So then my email got hacked and I lost contact with Victor and was recovering from my back surgery.  I had assumed that HP extended the warranty to two years.  that is until this latest issue started.  We found out the warranty ended after the first year.  As soon as the the warranty ended HP started initializing these BIOS updates that instantly caused severe stuttering and lag.  So bad that my son was unable to game anymore on his PC.  So we had to restore the PC to an earlier date and/or wipe PC clean.  We would do this and the stuttering and lagging went away and the PC was playable again.  However HP keeps initializing this BIOS update over and over and over again.  If we accept it, it makes the PC impossible to game on, if we cancel it, it just repeats again two hours later and will restart the PC when we decline.  So I don't know what to do.  I spent about $2,500 on a PC that has just been a nightmare for the entire time we had it.  I explained to the very nice claims employee named Victor that as nice as sending the PC in for a full refund was, it wasn't a solution for my son given the terrible time period we were in with my back surgery and the fact my son using his PC was all he would be able to do when I was recovering.  I assumed HP extended the warranty to two years based on the issues we had and that I told Victor we just couldn't send it in for a full refund because of our situation at the time, that the PC was working and that a two year warranty extension would best suit us at that moment.  Like I said this never happened and as soon as the one year warranty ended this strange BIOS update that renders the PC useless in terms of gaming is initializing on its own every two hours or so.  Please help us.  This is the first time I have been a consumer of an HP product and for $2,500 I am disappointed in the continuous issues my son has experienced with this PC.  especially since day one with the CPU liquid cooler being off the bracket and i forgot to mention earlier that I also had to reseat the RAM in the first week as well.  Thank you for taking the time to read this and I only want a fair solution.  The PC is able to game without any stuttering or lagging until HP forces this bios update.  Then my son can't game as the stuttering is so bad that every game is unplayable.  Then we have to spend the time to restore the PC to an earlier date over and over and over again.  HP initializes this BIOS update every two to three hours once we restore the PC.  This is strange and unacceptable.  I am grateful for any help and support.
