    Hi,

    I bought a 2009 8-Core Mac Pro in April (after sending back 6 iMac 27"s for yellow tinge issues), and soon after installed Windows 7 x64. Recently, Windows 7 seems to be crashing quite frequently, most notably whilst I am working in 3DS Max (2010) or After Effects (CS5). On occasion, it will BSoD, although usually all of my attached displays show extreme graphical corruption (static noise with various colored bars) followed by the Mac Pro rebooting. Before a crash occurs, I generally get a "warning" in the form of little graphical glitches in Windows. For example, black squares following the cursor, etc... Since first installing Windows 7, the cursor (attached to my Magic Mouse) has also been "getting stuck" briefly every ten-or-so seconds.

    I am positive that the Mac Pro is fault-free, as this has only ever happened under Windows 7 in Bootcamp. This problem is having extremely detrimental effects on my productivity, having lost several renders and scenes to corruption over the last week. I would be very greatful for any help anyone could provide, and I apologise for the long topic.

    Thanks,

    Troy,

    That sounds like bad RAM to me, especially since it's most common doing memory-intensive tasks. What type of applications do you run in OS X?

    In OS X, I usually run LightWave 9.6 and After Effects CS4/5. After Effects has often taken up around 14GB of my 16GB without incident.

    Six?

    Please tell me, is that a record for the amount of iMacs sent back by one person?

    I know many people have multiple GPUs in their mac pro. If this is the case I would see if windows 7 crashes after you go down to just one gpu. Mixing things like nvidia and ati in the same mobo is something I have never done windows side, and would never do. So if this is the case, give that a go.

    That sounds like an heating issue. Run smcFanControl (on osx) and change the speed of the fans. Reboot your machine into windows and try again.

    Probably.


    I only have one GPU (ATI 4870).


    Thanks, I will try that. :D

    Hi,

    I had something similar, but I can't remember if I had the graphical corruption before my system would hang. My issue resolved around the AppleHFS driver (that allows you to see the Mac HFS drive). I had to rename the AppleHFS.sys to something else and reboot. (do it in safe mode)

    rename c:/windows/system32/drivers/AppleMNT.sys to AppleMNT.sys or something similar.

    This was on my 2008 2.8 Octo system.

    Windows 7 can handle multiple GPUs from different manufacturers.
