Desktop Boot and Lockup

I Recently purchased an HP Omen Obelisk from my local Best Buy for 1 cent under $2000. From what I can tell it was a fairly powerful gaming tower with an intel 8700 and gtx 2080... However, I only used it to play World of Warcraft Classic. Now, anyone that knows World of Warcraft knows that it is not a graphically demanding game. One night during a leveling session in Scarlet Monastery my PC suddenly shut off with no warning. It tried restarting itself with automatic repair but a blue screen of death popped up DRIVER IRQL LESS OR NOT EQUAL with a website link to www.windows.com/stopcode

It restarted itself and several loud beeps came from the computer tower and not my speakers. When everything loaded a SYTEM SERVICE EXCEPTION NOT HANDLED error appeared and the PC restarted with several beeps after it repeated with the following errors followed by beeps. SYTEM THREAD EXCEPTION NOT HANDLED...........PAGE FAULT IN NON PAGED AREA..........DRIVER OVERRAN STACK BUFFER........ Finally a CMOS error and the cycle repeated itself. I tried loading safe mode but safe mode F8 is disabled on windows 10 (LOL WHY!?). Now I’m stuck where my PC tries to automatically repair itself but can’t because it gets a blue screen of death and I can’t do anything except look at an endless string of errors and my PC reboots itself over and over in an endless hopeless cycle  . Tried reseating the RAM and graphics card but man the graphics card was HOT like a few degrees short of burning my fingers HOT. I have no idea why it would be so hot when the computer had been basically dead for 4 hours. Anyway after that I ran several hardware diagnostics as that was the only thing I could get to work and they all came back fine. Now I have created a windows 10 recovery drive on a USB but I can’t seem to get the computer to boot from it. What do I do now ????
