Generic info on error, courtesy http://www.aumha.org/a/stop.htm
One of the many processes or threads crucial to system operation has unexpectedly exited or been terminated. As a result, the system can no longer function. Specific causes are many, and often best resolved by a careful history of the problem and the circumstances of the error message. One user, who experienced this on return from Standby mode on Win XP SP2, found the cause was that Windows was installed on a slave drive; compare KB 330100."http://support.microsoft.com/kb/330100
I would think hard drive...before exploring other hardware ideas.
FWIW: There is no master/slave setting for SATA drives.
I've been known to miss things...but I don't see those RAM modules listed under that board's Memory Support List. Not necessarily a deal-breaker, but can be such with some boards.http://www.gigabyte.com/products/product-page.aspx?pid=3912#ov
