The most recent dump is 1/30/2013:
KERNEL_LOG_FAILING_PROCESS:
PROCESS_OBJECT: fffffa80085cbb30
IMAGE_NAME: wininit.exe
DEBUG_FLR_IMAGE_TIMESTAMP: 0
MODULE_NAME: wininit
FAULTING_MODULE: 0000000000000000
PROCESS_NAME: wininit.exe
EXCEPTION_CODE: (NTSTATUS) 0xc0000005 - The instruction at 0x%08lx referenced memory at 0x%08lx. The memory could not be %s.
wininit.exe is a Windows program so unlikely to be the cause. My first suspect is defective memory.
Download
Memtest86+ (you want the 2nd one
Download - Pre-Compiled Bootable ISO (.zip)). Unzip it then create a CD from the iso file using your CD burning software. There is a good freeware burner called
ImgBurn which will do this easily.
DO NOT burn the .iso file directly to CD. It must be used as input to a program that knows what to do with it, like the one I mentioned above.
You can do this on any computer that has a working CD Burner.Boot the CD and run for at least 3 complete passes unless it shows errors sooner than that. An overnight run is even better.
