I've run into some serious issues with my used Lenovo Legion 5 (15ACH6H) gaming laptop that I bought at the end of 2023. It has an AMD Ryzen 7 CPU, an Nvidia RTX 3070 GPU, 16 GB of RAM, and two 512 GB NVMe SSDs (Samsung and Colorful). After two days of not using it, I turned it on to find it freezing every 30 seconds, which sometimes even disconnects my Wi-Fi. The temperatures seem normal, so it doesn't look like a thermal issue.
I checked the Event Viewer and saw warnings with Event ID 129 linked to my drives. After some trial and error to fix it, like changing power settings and updating drivers, I ended up caught in a BSOD loop with a SYSTEM_THREAD_EXCEPTION_NOT_HANDLED error (0x7E). I've tried booting in Safe Mode, which works fine, but I can't stabilize the system in normal mode. I even disassembled the laptop to clean it and replace thermal paste, but it's still giving me trouble. Right now, I'm stuck in a BSOD loop and can only boot into Safe Mode. Any advice on what I should do next?

You might also want to run a tool that gathers system info and logs from your Windows setup. There's a program called Specify that can help you do this. Just download it from the GitHub link, run it, and it will generate a report. Make sure to share that URL with us. It will give us better insights into what's going wrong with your system.
It sounds like a tricky situation! First things first, have you checked for minidump files? They can provide crucial information about what's causing the BSOD. You can usually find them under C:WindowsMinidump. If there are any files there, zip them up and share them on a file host like Catbox or Mediafire. We can analyze them to find the root cause of the crashes. Also, if you haven’t changed the dump settings, consider setting it to Small Memory Dump; it might help gather data without overwriting older dumps.
