There is no consistency to the crashes. This leads me to believe that the memory is becoming corrupt due to hardware issue or a buffer overflow in a driver.
Start --> Run --> verifier.exe
Create custom settings --> Select from individual settings from a full list --> Check off: Special pool, pool tracking, force IRQL checking, i/o verification, dma checking, and irp logging.
Select driver names from a list and select any drivers that are not from "Microsoft Corporation" and don't start with the work dump_.
If the system crashes again, post the most recent file in c:\windows\minidump (or wherever your windir is). Also, check that all your fans are clean. Overheating can cause weird crashes.
