  1. I installed Windows 7 and was constantly getting looping resets. I tested all of my hardware and everything came up clean.
    So, I reinstalled my OS and recieved another bsod.

    Attached is my dump file
    Any Idea?

    When you installed Windows 7 and reinstalled it did you update your video card drivers? Also, please tell us when the BSODs occur, i.e., internet surfing, gaming, randomnly?

    The errors are 0xD1 and these are usually caused by driivers. The driver specifically cited is the Nvidia display driver nvlddmkm.sys as the cause of your system crashes. Thus the reason for my question.

    Was your Windows 7 a clean install or an upgrade? And if it was an upgreade did you use something like Driver Cleaner Pro or Driver Sweeper to make sure all video card drivers were completely uninstalled before installing new vid drivers?

    It was a clean install
    I driver sweepered the drivers and reinstalled the drivers again and am still blue screaning. I believe im still getting an error pointing in the direction of my video drivers. Any idea? Could it be winfdows 7 lacking compatibility with the 7800 video card?

    This time it is an 0xA error and 0xA errors are caused either by hardware or drivers attempting an IRQ Level they should not be addressing.

    Unfortunantly this time it only cited a Windows OS driver and they are too general to be of much help.

    The question is are there drivers released for the 7800 for Windows 7. Certainly Nvidia should provide this information on their website.

    One other thing you could try is installing the driver previous to the latest one.

    Ive run a memtest, a stress test, and a bunch of other tests on my hardware ( With hirens) and everything came up fine.
    The most current drivers(the ones i have installed) say they support win 7. They are the only ones that say so, so imo i should stick with them.
    Should i wait till i BS again and post a dump? I dont think much is going to have changed problem wise though.

    Yes, let's see if you receive any more BSODs.
