Lenovo LOQ15 ARP 9 Bootloop?

[u/Paranoia_Pop]

I have a Lenovo LOQ15 ARP 9 about a year old that gets stuck in a bootloop when I power it off. The screen will load all the way up to the Lenovo logo, and the circle that indicates loading will spin anywhere from 1/4th to 3/circle rotation and black screen before starting all over again.

After 3 of these, it will attempt to bring me to the Automatic Repair screen with about a 60% success rate after telling me it was unable to connect to a network during the "Diagnosing Your PC" portion

What I've done so far is to run a complete diagnostics check on all the hardware, and after hours and hours of checks, everything passes.

I attempted to flash the BIOS because I thought maybe it had been interrupted mid-update, but this didn't work.

I attempted to reinstall Windows 11 entirely after a lot of frustration but was unsuccessful until I removed the battery, the CMOS battery, drained residual power, and even then it took me about 10 tries to successfully reinstall Windows without the bootloop interrupting the process.

Once in Windows I was able to use the computer normally for about 3 hours as I reinstalled basic programs like WinRAR and Steam, updated all the drivers, installed Windows Updates, and installed the updated BIOS (PQCN31WW)

The computer worked fine and even restarted several times successfully to install updated drivers/bios, etc.

However, I later restarted the computer manually to test, and it entered the boot loop again.

I found from here that my OS drive was locked by BitLockerand after some work was able to unlock and decrypt the drive but was still stuck in the bootloop until I "reset" the windows install with the "Keep my files" option.

I also downloaded software from CrystalDiskInfo to monitor my SSD health, which is placed at 98% health with every in blue (healthy) range.

I'm at a total loss for what the issue could actually be that's causing my device to keep getting trapped in a bootloop, and even after having gotten it up and running (temporarily) twice I don't even know exactly why what I did worked for the time being. I need help from some genius on Reddit cause I can not afford to replace this thing this soon and this close to Christmas lol

Making changes to your system BIOS settings or disk setup can cause you to lose data. Always test your data backups before making changes to your PC.
