My stationary computer with Windows 7 has a tendency to crash (basically, it reboots). It can crash in any situation, both when playing a game and when it's been idling for an hour. The only indication that it's about to crash is the sound of a disc spinning up. I'm guessing it's one of the hard drives somehow failing, and some seconds later the computer just reboots.
I want to investigate this further, so I'm wondering that if the OS somehow picks up on this crash before it happens (or perhaps the OS is even the reason the computer reboots), where would it log the error data?
