My friend hasn't been in town yet so I haven't been able to give me one of my RAM sticks but here is a mini update.
I had him run sfc /scannow last night for the hell of it since it was strange that the crashing was mostly gone for a couple days and then returned largely in the same fashion. He just texted me the results and long behold:
Windows Resource Protection found corrupt files but was unable to fix some of them. Details are included in the CBS.Log
I'd be getting him to check the system drive, can you get him to do a chkdsk c: /R from an admin command prompt. Best to warn him it may take many hours.
Yup i remember.. It might not be too drastic and often these corrupt files relate to something insignificant. The DISM scan should hopefully repair it but if not post in the CBS logs.
