Everything was working fine until yesterday, a video game crashed in the middle of a game. I couldn't restart it because Steam claimed it's still running, so I rebooted. But it didn't start up.
It was stuck at that moment where the screen turns off and back on during boot sequence. This time, it never came back on. Repeated several times and it's always the same. I managed to boot in safe mode and disable video card from Device Manager (I have a second, integrated Intel GPU in this laptop), after which the regular boot completed successfully, but I cannot enable video card now, because when I do, the computer freezes a few seconds later.
Already tried automatic boot repair, system restore (it failed), reinstalling drivers for both GPUs and updating BIOS. I don't know how to proceed with diagnosing the root cause. I'd like to avoid reinstalling OS if possible.
- Acer Aspire E 15 E5-575G-53VG
- OS: Windows 10 Home 64-bit
- CPU: Intel Core i5-6200U
- Integrated GPU: Intel HD Graphics 520
- Dedicated GPU: NVIDIA GeForce 940MX
Boot log: https://pastebin.com/hJ9heypy
First part is with NVIDIA enabled, hangs up and the log ends with a dozen null bytes. Second part is with NVIDIA disabled, boot completes successfully.
The issue is both at boot (when NVIDIA GPU is turned on during boot) and at runtime (when I enable NVIDIA GPU from Device Manager). Any way to debug the moment the computer hangs up in either scenario?
