When loading or creating a new project, my pc completely powers off and restarts within the first five seconds of the Editor window displaying. The only log I have found in Windows Event Viewer is “The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.” Do you have recommendations on anything to try or troubleshooting steps?
What I’ve tried so far:
Completely uninstalled Unity (manually removed all Unity registry keys + AppData folders) and then reinstalled.
Load tests on my GPU + CPU to rule out hardware issues. Memory test for bad RAM + Check disk for hard drive failure.
System Specs:
Unity 5.5.0f3 64bit
Windows 10
i7, gtx 1070, 16gb ram
Are there any Unity logs or utilities that could assist in troubleshooting the problem? Next steps before completely reinstalling windows?
Edit: Just installed Unity 5.0.0, which runs without crashing. Not sure which version between 5.0.0 and 5.5.0 introduced problems.
That sounds very strange. Was anything in the log file? Unity - Manual: Log files
I installed Unity version 5.4.2 and was able to load projects. However, it still sporadically shut down the computer when importing packages. Looked through the logs and nothing stood out for reason it’s crashing. I still haven’t ruled out the possibility that it could be a hardware error, but other than Unity my computer runs stable. About a year ago I had Unity installed on this PC and never had problems.

For anyone who stumbles upon this post in the future,
The issue was resolved by flashing my motherboard bios to a new version that improved compatibility with my processor. (F6 > F10 if you happen to have the Gigabyte z97x-UD5h motherboard and i7 4790k)

Konbonix… you are a god. Been having issues with my PC crashing on intensive apps like games, photoshop, and unity for the last year or more. I have the same CPU and motherboard setup and had the same issue, and applied the same fix with success. Thank you!!
