Guess you get a bluescreen but you got the option enabled that it immediately reboots (option can be changed in your systemsettings->system). Bluescreens can only be caused programs running in ring 0 (like drivers) and not by applications).

Typical sign for an unstable system. When validating a chd, your cpu/ram will be used much more intensive than by any normal application or game.

This is usually caused by:
- bad ram, bad ram timing, overclocked system, buggy via chipsets, bad idecables.
