Shut down = power issue. Basically, the only thing that can cause a spontaneous instant shutdown (all power goes off and stays off) is a power supply triggering a fault protection to avoid damage. Well, that, or a motherboard that somehow triggers the PSU shutdown, but haven't actually heard of such a case ever...
Reboot = you'd have to disable the automatic reboot in Windows control panel/System to get the blue screen up instead of reboot. Then, based on what that blue screen actually says, it might be possible to figure out what the problem is.
