    I need your help, I'm experiencing random overnight crashes, always similar to below minidump (below) results (iastor.sys is implicated) but cant figure out what brought it to this point. System is up to date, iastor.sys hasn't changed since 2/1/2012. Ran Malwarebytes and Norton360 scan. System is clean otherwise.

    If this is a laptop make sure you have the breath holes uncovered as your system could be heating up. If the system had too many heat up events, the CPU could be damaged and just crashes when it gets a particular load. I hope this information helps.

    drmacpccom, thank you for your reply. This is a dell tower. No overheating problem present. We need to look quite a bit deeper.

    sfc /scannow and chkdsk show no problems either.

    Thanks again.

    Best,

    Motohed

    Thank you too for responding captainron276. I followed the link you recommended, don't see a correlation. The system has since developed a volume shadow copy problem that I'm trying to track down as well, could be related. Currently the VSS fails on backup of drive G: (the disk has volume c: (boot), d: (recovery), g: (data). G: is currently flying naked with backup failing when either trying a acronis 2010, a windows system backup, or even disk2vhd, only the C: partition is backed up. In fact disk2vhd is a real easy way to force the problem to happen:

    My event viewer events saved to a file uploaded for anyone interested.

    Thanks in advance for the help...
