    I suggest the following steps for changing your ATI driver.
    Download the driver you want to install.
    Download Driver Sweeper from Guru3D & install it.
    http://www.guru3d.com/content_page/guru3d_driver_sweeper.html

    Control panel > programs & features; remove / uninstall ATI graphics driver
    Boot to safe mode
    Run Guru3D
    Install new driver
    Boot to normal mode

    I have a Dell Vostro computer. I began receiving BSODs referencing the nVidia graphics driver.
    I downloaded the latest nVidia graphics driver from Dell.
    Followed the steps above.
    Same problem
    Downloaded the latest graphics driver from nVidia; followed the steps above; same problem.

    I downloaded an older driver from nVidia; followed the steps above; NO BSODs! :D

    Best of success.

    Keep us posted.

    I will try this. I just finished a workout, 60 minutes, no BSODs. :D

    I have also noticed BSODs as I've been installing all the MS recommended updates as well. I'm going to install them one-by-one to determine which one is causing my system to blue screen. I'll post the lastest dump log as well.

    Thank you:)

    If you provide the minidump as a .zip, I will be glad to analyze it.

    I'm not trying to be difficult. I don't do .7z & .rar .
    RIGHT clcik the file. Left click "send to"
    Left click "compressed [ zipped ] folder"

    Excellent idea.

    BSODs after a format & fresh install concerns me.

    Which hardware diags have you run during the past 45 days? Please provide approx dates.
    #15 of this thread.
    Have you fixed it?

    #28
    Which diags? Dell's from their boot menu?

    Please report the status of the diag lights, that I had mentioned, #3.
    You, #32
    Did you replace the DVD drive?

    You, #41.
    Have you replaced the HDD & ram?

    I suggest that you run the HDD from the HDD manufacturer & the ram diag [ memtest86+ ] run memtest86+ for at least 8 hours or until an error appears.

    Is this your computer?

    Just thought I would jump in and analyze the Crash Dump. It is dated 22nd February, have you had any more? It shows Pool Corruption which is usually a driver or faulty memory.

    As you have replaced the hard drive and DVD drive/s and done a clean install (I assume that's what you did or was it from an image back up) the most likely cause will be due to other drivers that you have added or faulty RAM.

    The system shows as still being on Windows 7 without Service Pack 1 being installed, go to this link and follow the instructions to install the whole package in one go, it will save a lot of time as it includes all previous updates. How to install Windows 7 Service Pack 1

    When Windows is completely up to date lets see if any more BSOD's occur, post the Crash Dumps as they happen.

    What RAM have you got installed, I suspect you have more than one stick so if the BSOD's still happen remove all but one of the sticks and continue running the system to see if you get any more crashes, if you do swap the sticks around. Continue until all sticks are tested. You cannot assume just because the RAM passed a diagnostic test that it is 100%, I've seen RAM pass tests before only to find, using the above method, that a stick was faulty.

    If that doesn't find the RAM is to blame then I can post instructions to run the Driver Verifier.

    Hi Mark, ding ding ding and you win the prize!:D Whooo hooo. I had multiple problems and here is the fix:

    1) I had Cosair RAM, 4 sticks to be exact; they've been replaced. Oddly enough they tested clean the first two times I ran diags. The mini screen on my XPS showed a BAD RAM error LOL
    2) I had a defective DVD player which also causes issues; I've replaced that player and am running dual DVD players which is great
    3) Catalyst Control Center (CCC) from AMD put out a bad package. There are people all over having BSODs as it appears to be stepping on the .NET files during install.

    Here is what I did to fix:
    1) Installed a fresh copy of Win7 64-bit
    2) Installed all service packs and hot fixes
    3) Allowed Windows to install a native video adapter driver
    4) Went to device manager and removed the adapter
    5) Went to the AMD site and downloaded the latest drivers for my new video card
    5) Rebooted
    6) Ran the AMD install using the custom install and deselected the sound driver and rebooted

    I've been running clean ever since. I did get one notice that the SP wasn't install after I installed CCC. I allowed the conflict to resolve itself and allowed the updates to install via Windows update without my intervention.

    Thanks for the post, it came in just as I figured out the bad RAM!. (y)

    Congratulations!

    It is common for hardware failure to be preceded by intermittent function and intermittend failure.

    Thanks for posting the steps that resolved your computer issues.

    When satisified with the status of the computer, please mark your thread solved.
