    I am running

    4x2gb Kingston 800 ddr2
    GA-EP45-D54P Mainboard
    Thermaltake Toughpower 750W
    2x ASUS EAH4850 W/Crossfire

    I can access windows until i install the graphics drivers. Then i get BSOD.
    Go to Safe mode, uninstall the drivers and i can get in to windows again.
    Tried flashing mainboard bios to no avail.
    Tried disconnecting Crossfire to no avail.
    Tried taking one graphics card out to no avail.
    Tried Installing the drivers without the CCC software to no avail.
    The cards come with Glaciator fan sinks which work fine, keep the cards down to about 40C(102F)
    Am starting to think that the Mainboard just isn't compatible with these cards, although it does say that it is crossfirex enabled.
    I'm thinking it's not a Power supply problem as it has dedicated rails for the PCI-E connectors
    On the BSOD it says Attempt to reset the display driver and recover from timeout failed and in particular mentions ATIKMDAG.SYS
    Visited ATI website and this is what they say

    Symptoms:
    After installing the Catalyst display drivers and rebooting, the system will give a blue screen (BSoD) error referencing ATIKMDAG.SYS

    Cause:
    This issue is caused by using a motherboard with a chipset that is unsupported in Windows Vista


    Surely motherboards that are released now should be compatible with the graphics cards that are released now.
    I'm really running out of things to try, anyone care to help??

    Have you flashed the bios of your 4850s by any chance? There's no way the P45 chipset isn't supported by vista. I've got a P35 and X38 that both work perfectly fine in windows vista 64 and 32bit. With my X38 board having 2 4850s crossfired in it.

    If you haven't flashed the 4850 bioses, I'm guessing it's a non-reference overclocked one? It could have a b0rked bios on it or something maybe?

    good thought

    No i haven't tried flashing the bios on them. i wouldnt have the slightest clue on how to do it. Would you be able to point me in the right direction ? and they're straight from the box. i don't think it's overclocked or anything. pretty sure they're just stock standard. They're ASUS EAH4850..
    Thanks.

    Did you just install the drivers that came with the card? If so, uninstall those, then download and install the latest ATI drivers.

    Are these the first cards on the system? Possible some remaining nvidia drivers remain?

    i cant see both cards being faulty, tbh i would probably try a reinstall of windows at this point and see how that goes, to be getting bsod of both cards seprately is weird, maybe a driver conflict ?

    If you are able to get back into Windows, go to Control Panel-->Administrative Tools-->Event Viewer and check there for errors and or warnings.

    Uninstall all traces of ATi related material. Once you have done the uninstall, use driver cleaner. It will remove all dead reg keys associated with ATi. Once that is complete, download only the Driver package from ATi.

    32-bit Vista Drivers

    64-bit Vista drivers

    Reinstall from those. I hope it helps you. If you need more help, we're here.
