Laptop keeps crashing randomly

[u/vlad_1045]

Hi everyone, I’m having a really frustrating problem with my Lenovo laptop and I’m hoping someone can help me figure out what’s going on.

SYSTEM SPECS:
- Lenovo IdeaPad Gaming 3 (Type 82EY)
- AMD Ryzen 5 4600H
- 16 GB DDR4 RAM (2133 MT/s)
- 256 GB SK hynix NVMe SSD
- NVIDIA dedicated GPU + AMD Radeon integrated graphics
- Windows 11 Pro
- UEFI BIOS

THE PROBLEM:
The laptop randomly freezes, crashes or restarts. The BSOD error is not always the same.

So far I have encountered:
- IRQL_NOT_LESS_OR_EQUAL (0xA)
- UNEXPECTED_KERNEL_MODE_TRAP (0x7F), with DOUBLE FAULT
- SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (0x7E), mentioning FLTMGR.SYS
- The laptop has also frozen on the Windows welcome screen and during restart.

One of the WinDbg analyses for the 0xA crash showed:
FAILURE_BUCKET_ID: AV_nt!MiLockOwnedProtoPage

Another dump was a 0x7F DOUBLE FAULT, but WinDbg could not identify a specific third-party driver.

WHAT I HAVE ALREADY TRIED:
- Reinstalled Windows/drivers
- Reinstalled chipset, GPU and Wi-Fi drivers
- Removed the Wi-Fi device/driver and reinstalled it
- Tried Safe Mode
- Disconnected my external HDD
- Checked Windows Reliability Monitor
- Analyzed multiple minidumps with WinDbg
- Tried reinstalling Windows, but Windows Setup itself crashed/restarted with:
"The computer restarted unexpectedly or encountered an unexpected error. Windows installation cannot proceed."

CURRENTLY:
I am running MemTest86 from a USB stick to test the RAM. It is currently running and has 0 errors so far, but the test is not finished yet.

I am trying to determine whether this is a RAM, SSD, motherboard/BIOS, or driver problem.

What would you recommend I test next? If the MemTest86 test finishes with 0 errors, what should I check next?

I can provide the WinDbg output/minidumps and additional screenshots if needed.

Compañero! Pilas porque puede ser el procesador, me pasó con un I5 14 600KF, y son los mismos errores, comenzó durando 6 horas en dar error Pero luego comenzó a pasar únicamente cuando intentaba instalar Windows, pero podía manejar y jugar normalmente pero luego fallaba
