so my computer started unexpectedly shutting down about 60 seconds after loading windows today. No BSOD, no error message, no warning, just a hard shutdown. It happened consistently every time I started the computer, unless I was in safe mode, then I had no issues. So I went into msconfig, and eventually tracked the problem down to a specific system service - "power". If that process is stopped, no hard shutdown. But that process seems to be responsible for Windows Audio Endpoint Builder, so I have no audio if it is stopped. Can anyone think of any reasons for this process to cause an unexpected shutdown? and how do I go about fixing it?
