Troubleshooting Windows Installation Failures

Hi everyone! I've been having a really tough time with my computer. Two days ago, after I finished dinner, my PC was unresponsive and stuck on a black screen. When I tried rebooting, it got caught in a loop of automatic repair that just wouldn't end, and I kept seeing an error saying "Startup Repair couldn't fix your PC". I tried a bunch of different solutions: reverting updates didn't work, and commands in CMD like bootrec /rebuildbcd just showed "Total identified Windows installations: 0". Safe mode led to a blue screen with an "inaccessible_boot_device" error. Next, I thought a clean install might help, so I wiped my drive and used a bootable USB to reinstall Windows. Unfortunately, the installation kept failing at various points—most frequently around 11%, but once it got to around 30% before halting with an error about the installation failing. My friend suggested it could be a faulty SSD, so I bought a new one (Samsung 990 EVO Plus 2TB NVMe SSD) but still ran into the same installation error, just at 45% this time. I even tried different M.2 slots on the motherboard, but it didn't change anything. Currently, ACHI is enabled, Secure Boot is off, TMP 2.0 is on, and XMP is off. I reseated the RAM as well, but nothing has worked so far. Lastly, I had issues creating a new bootable USB on my MacBook, but I plan to give that another go tonight. I'm really at a loss here! Any help would be greatly appreciated! Thanks!
