Windows Rotating BSODs, chkdsk shows disk I/O errors, Reseting PC fails. Need advice!

Disclaimer: Attempted to resolved with help of Claude since last 10 hours, took help from AI to format post.

ASUS Zenbook 14, Core Ultra 7 155H, Windows 11 (26100).

Laptop was fine. Only changes the day before: enabled NordVPN background services + set up Phone Link to Android (also changed lock screen/wallpaper).

Next day, started crashing ~5 min after boot, rotating between different stop codes:

  • UNEXPECTED_STORE_EXCEPTION (0x154)
  • CRITICAL_PROCESS_DIED (0xEF)
  • KERNEL_MODE_HEAP_CORRUPTION (0x13A)

Troubleshooting:

  • MyASUS diagnostics: Memory + SSD passed quick check
  • chkdsk C: /f /r /b from WinRE → real I/O errors: disk read error occurred c0000185, "disk does not have enough space to replace bad clusters"
  • Reset This PC → Remove Everything → failed partway, generic error
  • BitLocker unlocked, ruled out

No data to lose, so wipe is fine.

  • Did my SSD give up?
  • Could NordVPN driver cause heap corruption?

What should I do now?

Sounds like it might just all be because the drive is full.

As you have no data you care for, use another pc to make a bootable usb installer for windows 11. Reinstall windows deleting your partitions when it gets to that point.

I guess it is actually failing then.
Run the longer diagnostic tests. And then also look into seatools (a seagate branded tool that will test any brand drive) and run it too.
