I'm on a Lenovo Legion y540 81sx, with an intel 512gb m.2 pcie nvme 660p ssd.
When my pc is performing demanding tasks like playing a high end game, after a few minutes it will freeze, then bluescreen with a device_setup_manager code, followed by ,,default boot device missing or boot failed'' screen in the bios.
Restarting fixes this, and the laptop works normally, as long as its not demanding.
In the event viewer I see a ,,Metadata staging failed, result=0x80070490'' error.
Now I'm wondering if its a failing ssd or overheating and restarting, as I didn't change the thermal paste for a long time and it can get to above 85 temps.
